已知函数f(x)=log以a为低x的对数(a>0,a≠1)的反函数是f-1(x),且满足0
已知函数f(x)=log以a为低x的对数(a>0,a≠1)的反函数是f-1(x),且满足0
已知函数f(x)=log以a为低x的对数(a>0,a≠1)的反函数是f-1(x),且满足0
已知函数f(x)=log以a为低x的对数(a>0,a≠1)的反函数是f-1(x),且满足0<f-1(2)<1,则函数f-1(x+1)的图像大致是
解析:∵函数f(x)=log(a,x) (a>0,a≠1)
其反函数f^-1(x)=a^x
又0<f-1(2)<1, 即0<a^2<1==>0<a<1
将反函数图像左移1个单位得到f^-1(x)=a^(x+1)的图像

3, Second difference is virtually no difference compared with yesterday. However, compared with three days still to heavy volume.
case of a
key;
six, if this form of k lines near the head in early, often, there will be two trends;
(1), ie the share price will not be open much higher, generally below 2%, and the morning rose rapidly rises more than 7% or more often, and then the afternoon price the slow down.
(1), although a higher open early that day, but with sideways is not high, but the day of rapid decline.
shown above;
3, the operating cycle is often an end in the next day, the longest no more than three trading days.
shown above;
shown above;
2, is often a strong second day of heavy volume would rise more than 8% above the general rate, the daily limit version for more.

shown above;
1, 5,10,30 long moving average order, and all the moving average trend is up, numerical increase in size.
(3), as with the previous few stocks, often making the rate increase the whipsaw. Facing short-term stock price fell, the latter is often a market.

that appear often in the form of a breakthrough at the beginning of the whipsaw whipsaw day intraday volatility is the main purpose of the stock will not be too general amplitude of transactions modest amount compared with yesterday, amplification, late fall is mainly produced at the same time covering Yinxian K line gap is often closed yesterday above the K line of most entities. Down to create the illusion of high heavy volume.
shown above;
(3), the same day as long as the form is true Gaokaidizou Yinxian, often deliberately created by the dealer, and such stocks tend to break out again late rally.
(4), whether ascribed or down, the amplitude of the day is not too large.
2,Oakley sunglasses, the high price point of just breaking previous platform.
II, to appear.

failures following the trend, the trend of the day, there will always be some one does not meet the above conditions.

case eight
(2), fell during the afternoon and did not cover the estimated shortfall, short-term trend of further decline. However, from another dealer whipsaw rate also shows deep, post-outbreak market also is not small.
(5), to close at yesterday's closing price closing above the best, do not form a gap for the best.
(2), as long as the formation of real Gaokaidizou Yinxian, often making the whipsaw action, and this also shows that the dealer will often come back later.
(3), this trend would break out late often means a good market.
case nine
1, the next day waiting for a 5 day drive prices in the online shift.
(2), the day down k k lines cut into the line of yesterday's magnitude is too large, reached the half.
(1), shares face the pre-head, large selling pressure.
(2), early on the decline, and then has been weak finishing. While short-term do not have the strength quickly, but later often broke out after the stock market stabilized.
(2), high stock price has not appeared this trend often want to put a lot of manufacturers to bring out the trend leads to whipsaw Yinxian purpose, let loose highs stuck disc, and often after such a trend to deepen Xipan range.
These are success stories, we must grasp every detail of the conditions, careful experience.
1, Represents the trend of bigger gains, the stronger, the more favorable today.
(1), opened higher open between 2-3 points the best.
(1), shares Tiaokonggaokai, was rushed to the daily limit on the edge. The day of the amplitude is too large.
(2), high price does not really open much, just slightly higher open and then quickly cover the gap.
shown above;
Shenma Industrial (600810) on 17-18 June 2009 the trend
(3), a higher opening price the day after the time-sharing plans if the trend can be maintained in the high open area in the shock box is the key.
Fourth, the share price and about 2% higher opening day, shot up a strong range of 8% up after the fall, the amplitude is too large.
(2), is the rapid decline in share prices opened higher after covering the gap, and then in the reverse shock in a certain space.
Third, the rapid decline in early trading after opening higher, covering the morning and put upward gap.
(2), high stock prices fell rapidly after opening, and then maintain the cabinets in a shock, this trend is often the makers of the whipsaw action. Means that there will be late fall, after stabilizing the rally.
(1), although a higher open early that day, but with sideways is not high, but the day of rapid decline.
(2), shares in the afternoon of July 16 fell during the upward gap is not covering.
(1), did not markedly higher stock prices, a strong up day rate shot up to 8%, and then down quickly.
(6), the day stock price movements are often time-sharing in the last half hour started to decline.
(1), facing the pre-head, selling pressure will be relatively large.
seabirds Development (600634) on 3 July 2009, 6, the trend, the trend from the two days can be summed up;
classic example of the trend from the above summarized as follows;
II k line cut down day yesterday, the magnitude of k line is too large, reaching the half.
(1), the rapid decline in early trading after opening higher, covering the morning and put upward gap. (Does not meet the conditions for rapid strength)
(4), if stock prices opened higher after the morning covering the gap, often later also continue to adjust. On the contrary, with rapid short-term strength of the stock within two days are often the last half an hour in the late afternoon began covering the gap.
(1), high-impact opening up quickly rose 8% to close to the location, and then quickly back down.
Case III
as shown; Northern shares (600,262) at August 3, 2009, 4 (buy) the trend
a day,Oakley sunglasses cheap, although a higher open early, but with sideways is not high, but the day of rapid decline.
(1), the high price does not open, but the flat open.
shown above;
(2), the day down k k lines cut into the line of yesterday's magnitude is too large, reached the half.
Case II
case four
Third, post-trend.
four principles of analysis.
2,mac brush set, And remain until the morning of the closing time-trend fluctuated near the moving average, down phenomenon occurs in the late day, the formation of K line engulfing Yinxian, closing yesterday's closing price in the vicinity.
(1), shares open higher after rapid finished lower if the formation of k-wire line to bring forms (heavy volume Yinxian), and the formation of upward gap, often short-term stock price will fall, but often just making efforts to increase the whipsaw, and as long as the share price fall to stabilize, the trend began to reverse, and gradually began to moderate heavy volume, they often think that this post will be the big move.
(2), a sharp drop in the morning can not.
five, the stock has not opened higher, but the flat open.
(2), shares the real high open between 2% to 5% of the stocks the most powerful, often have a greater chance of late.
