1. f(x)=4/(4x-3) what does f^-y equal? 2. h(x)=3-(x+5/x-7) what is h(9)^-1? 3. f(x)=x-1/x^2+1 g(x)=x+10/x+13 What is (f o g)(x)? and what is What is (g o f)(x)? 4. h(x)=square root of (1/x^2+7) + 16 if f(x)=square root of x, then find a function g such that h=f o g if f(x)=square root of x+16, then find a function g such that h=f o g. Don't have any resources available at the moment, but need some help haha.
