f(x+1)=3x^2-x+1怎样算

f(x)=3x-(1-x) 怎样求导 f(x+1)=3x^2-x+1怎样算 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) 函数对应法则3f(1-x)+f(x)=(1-x)^2 怎样得出f(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 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
