若F(X-1/X)=X^2+1/X^2,求F(X-1)若F(X-1/X)=X^2+1/X^2,求F(X-1)若F(X-1/X)=X^2+1/X^2,求F(X-1)F(X-1/X)=X^2+1/X^2=
若F(X-1/X)=X^2+1/X^2,求F(X-1)
若F(X-1/X)=X^2+1/X^2,求F(X-1)
若F(X-1/X)=X^2+1/X^2,求F(X-1)
F(X-1/X)=X^2+1/X^2=(x-1/x)^2+2*x*(1/x)=(x-1/x)^2+2
令Z=x-1/x,则原函数可写成:
F(z)=z^2+2
令z=x-1,代入上述函数,则有
F(X-1)=(X-1)^2-2=X^2-2X+1+2=X^2-2X+3
看懂了吗,
你是个人才。不懂。
若f(x)满足f(x)-2f(1/x)=x,则f(x)=?
若F(x)满足f(x)+2f(1/x)=x,则f(x)=
f(x)={2x+1,x
f(x)={1+x/2,x
f(x)=(x-1)/(x+2)
f(x)+f((x-1)/x)=2x; x!=0,1; 求f(x)
f(x)+f[(x-1)/x]=2x x不等于0,1.求f(x).
max{f(x),g(x)}=1/2(f(x)+g(x)+|f(x)-g(x)|
若函数f(x)满足f(x)+2f(1/x)=5x+4/x,则f(x)=
若一次函数f(x) 满足f[f(x)]=1+2x 求f(x)
若F(X-1/X)=X^2+1/X^2,求F(X-1)
若f(x)=(x-1)(x-2)...(x-2010)(x-2011),则f'(1)=
若f(1/x)=x+根号1+x^2 (x>0),则f(X)=
若f(2x+1)=x*x+x,则f(x)
f(x)满足:2f(x)-f(1/x)=x+1,求f(x)
设函数f(x)满足f(x)+2f(1/x)=x,求f(x)
已知f(x)满足2f(x)+f(1/x)=3x,求f(x)
F(X)满足F(x)+2f(x分之1)=3X,求f(x)
