Question

What would be the values of f(f-1(17)) and f-1(f(2))? FAST HELP

Answer 1

f(f-1(17)) = 17

f-1(f(2)) = 2

Explanation:

Lemma;

If f(x) and g(x) are inverses, then the compositions f(g(x)) = g(f(x)) = x.

In both situations, we are determining the composite of inverse functions;

f and f-1
