The table below shows some inputs and outputs of the invertible function fff with domain all real numbers.
x | 5 | 3 | 1 | 18 | 0 | 9
f(x) | 9 | -2 | -5 | -1 | 1 | 11
Find the following values:
f^-1 (-2)=
f^-1 (-1)=

The value of is 3

The value of is 18

Explanation:

Given that the set of inputs and outputs of the invertible function f.

We need to determine the values of and

The value of :

We need to determine the image of the y - value -2.

The image of the y - value (-2) is the corresponding x - value from the given table.

Thus, from the table, the image of -2 is 3.

Hence, the value of is 3.

The value of :

We need to determine the image of the y - value -1.

The image of the y - value (-1) is the corresponding x - value from the given table.

Thus, from the table, the image of -1 is 18

Hence, the value of is 18.
