Question

Let g be a one-to-one function and suppose f is the inverse function of g

if g(5)=11 and g(3)=5, find f(5)

Answer 1

Answer: 3

Explanation:

If f(x) = y, then invf(y) = x
So, f(5) = invg(5) = 3

Answer 2

So g(6) comes out to be 2.

Explanation:

So f(6)=5 means when f acts on 6, the result is 5....so the inverse would take 5 back to 6...or g(5)=6

So f(2)=6 means that f reassigns 2 to 6....so the inverse would take 6 back to 2....or g(6)=2

hope this helps :)
