Question

If (20, 14) is an ordered pair of the inverse of F(x), which of the following is an ordered pair of the function F(x)?

Answer 1

All you need to do is to reverse the order of the coordinates 20 and 14.

Answer 2

Hint:
If g(x)=x+4, then (3,7) is an ordered pair of g(x).
Find the inverse of g(x) :\(g^{-1}(x)\)
1. x=\(g^{-1}(x)\)+4
2. \(g^{-1}(x)\)=x-4
So \(g^{-1}(7)=7-4=3\) which means that (7,3) is an ordered pair of \(g^{-1}(x)\).
