f(x)=4^x-2^(x+1),(x大于等于1),求f-1(0)

f(x)=大括号2x x大于0 f(x+1) x小于等于0.求f(-2) f(x+1)+f(x-1)=2x²-4x,求f（x）? f(x+1)+f(x-1)=4x^3-2x求f(x) 已知f(x)={f(x+2),x≤-12x=2,-1＜x＜12的x次方-4,x≥1解不等式：{x≥-1f（x）≤2“{”是大括号， 二次函数f(x)满足f(x+1)+f(x-1)=2x^2+4x,求f(x) 若函数f(x)满足f(x)+2f(1/x)=5x+4/x,则f(x)= f(x)={2x+1,x f(x)={1+x/2,x f(x)=(x-1)/(x+2) 怎样由f(x+2)=1/f(x)得出f(x+4)=f(x) 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 已知f(x)={2^x,(x≥4);f(x+1)(x 设函数f(x)={(1/2)^x(x≥4),f(x+3)(x 数学f(x)=x(x+1)(x+2)(x+3)(x+4)(x+5),求f'(0)=? f(x)=x(x-1)(x+2)(x-3)(x+4)……(x+100),求f'(1) 已知f(x)=x(x-1)(x-2)(x-3)(x-4)(x-5),则f‘(0)为 f(x)+f((x-1)/x)=2x; x!=0,1; 求f(x)
