Question

If g(x) is the inverse of f(c) what is the value of f(g(2)) ?

Answer 1

2

Explanation:

An inverse of a function is a reflection across the y=x line. This results in each (x,y) point becoming (y,x).

x f(x)

-6 1

-3 2

2 5

5 3

8 0

So the inverse becomes:

x Inverse

1 -6

2 -3

5 2

3 5

0 8

g(2) = -3 and f(-3) = 2.
