Answer:

Choice D is correct. Every x-value corresponds to exactly one y-value.

Explanation:

We have given the set of ordered pairs :

{ (-5,-5) ,(-1,-2),(0,-2),(3,7),(8,9) }

We have to explain that is this set represent a function or not?

Function is a rule that assigns each input exactly one output.

In the set, each value of x has unique value of y.

From the definition of function,this set represent a function because each input has a single output.

Every x-value corresponds to exactly one y-value.

Answer:

D. Yes,because every x-value corresponds to exactly one y-value.

Explanation:

The given ordered pairs are;

{
(-5,-5),(-1,-2),(0,-2),(3,7),(8,9)}

We do not have the same x-value corresponding to more than one y-value.

We can see from the ordered pairs that every x-value corresponds to exactly one y-value.

Therefore the graph of this relation will pass the vertical line test.
