1.f(x)=1-x² 2.f(x)=-3x+1 3.f(x)=2/x 4.f(x)=(x-x²)/
2f(x)+x^2f(1/x)=(3x³-x²+4x+3)/(x+1) 2x²f(1/x)
F(X)满足F(x)+2f(x分之1)=3X,求f(x)
已知f(x)满足2f(x)+f(1/x)=3x,求f(x)
已知f(x)满足2f(x)+f(1/x)=3x,求f(x)?
已知f(x)满足2f(x)+f(-x)=-3x+1,求f(x)
f(x)=x(x-1)(x-2)(x-3)(x-4) f'(1)=?
f(x)=x²+3x|x-2|
f(x-1)=x^2-2x+3(x
f(x)=(x-1)(x-2).(x-3)求导
已知f(x+1)+2f(-x)=3x²+x,求f(x)
F(x)=3x^2+2x-1 求F(x+△x)-f(x)/ △x
