The relation of the function of x is the fourth function.

We have to determine which relation is a function of x.

According to the question

To determine the function of x following all the steps given below.

1. The given values of x are -1, 2, 2, 3.

At the value of x = 2 the value of y = -9 and 8.

For the particular value of x, the value of y is always different.

2. The given values of x are -8, -8, 1, 1.

At the value of x = -8 the value of y = -9 and 2.

At the value of x = 1 the value of y = -9 and 2.

For the particular value of x, the value of y is always the difference.

3. The given values of x are -5, -5, -5, -5.

At the value of x = -5 the value of y = -1 and 7.

At the value of x = 5 the value of y = -9 and 2.

For the particular value of x, the value of y is always different.

4. The given values of x are -3, -2, 4, 7.

For the value of x the different value of y.

Hence, The relation of the function of x is the fourth function.
