If f(x)=[2x]-4x with domain 0

If f(x)=[2x]-4x with domain 0 If g(f(x))=2x+1 and f(x)=1/4x-1,then g(x)= 英语的啊 大概是高一的水平就可以了If the graph of the f function is a line with slope 2 ,which of the following could be the equation of 五个选项(A) f(x)=4x-2(B)f(x)=2x+4(C)f(x)=-2x-2(D)f(x)=(1/2)x+2(E)f(x)=(-1/2)x+1/2 If f(x)=4x+1 and g(x)=x^2-3x+1,then (f+g)(-2)=? f(x)=x^2+x (x f(X)=f(X+2)(x 设f（x)满足f(-x)=-f(x),f(x)=f(4-x),x∈[0,2)时,f(x)=x,则f(11.5)等于? f(x+1)+f(x-1)=2x²-4x,求f（x）? f(x+1)+f(x-1)=4x^3-2x求f(x) f(x)=min{x^2-2,x,4-x} 怎样由f(x+2)=1/f(x)得出f(x+4)=f(x) f(x+2)=-f(x)怎么得到f(x+4)=f(x)? f(x)= 4-x^2 ,|f(x)|2求f(f(x)) 若函数f(x)满足f(x)+2f(1/x)=5x+4/x,则f(x)= 二次函数f(x)满足f(x+1)+f(x-1)=2x^2+4x,求f(x) 给出一个算法：READ X IF X≤0 THEN f（x）←4x ELSE f（x）←2的x次方 END IF PRINT f（x） 根据以上算 函数f(x)={(1/2)^x,(x>4),f(x+3),(x 函数f(x)={(1/2)^x,(x>4),f(x+3),(x
