Invertible functions are functions whose inverse can be calculated.

The values of the expressions are: and

The table entry is given as:

x | 5 | 3 | 1 | 18 | 0 | 9

f(x) | 9 | -2 | -5 | -1 | 1 | 11

(a) Calculate f^-1(f(5))

Start by calculating f(5).

From the table, we have:

Take inverse function of both sides

From the table, the inverse value of 9 is 5.

i.e.

So, we have:

(b) Calculate f(f(5))

In (a) above, as have:

So, the function becomes

From the table, the value of f(9) is 11.

So, we have:
