f(x)=3^(2-x^2),(x

f(x+2)>=f(x)+2,f(x+3) 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)=f(X+2)(x f(x)=x(x-1)(x-2)(x-3)(x-4) f'(1)=? f(x-1)=x^2-2x+3(x f(x)=(x-1)(x-2).(x-3)求导 f（x）=x²+3x|x-2| 已知f (x)+2f(-x)=x^3+x^2,求f(x) f(x)+2f(-x)=3x+x的平方,则f(x)等于
