Algebra-1

To determine if this relation is a function, we need to check if each x-value is associated with only one y-value.

For x = -5, the y-value is -15.

For x = -1, the y-value is 5.

For x = 4, the y-value is also 5.

Now, according to the definition of a function: Each x-value must have exactly one corresponding y-value.

In this case:

x = -5 is paired with y = -15.

x = -1 is paired with y = 5.
