Question

if h^-1(x) is the inverse of h(x) what is the value of h^-1(h(x))
A. X
B. 1
C. 0
D. X^-1

Answer 1

Often when we apply a function f and then its inverse f^(-1) we get our original value back so mathematically this means \[f(f^{-1}(x)) = x\]

Answer 2

So what do you think would happen if you had \[f^{-1}(f(x))\] same result as above or different?
