Answer:

No, D

Step-by-step explanation:

One definition of a function is that there cannot be 2 different points on the same x line with different corresponding y values, another way of putting this is if 2 points lie on the same vertical line it is not a function.

Answer:

The answer is D.

Step-by-step explanation:

This is because a function cannot exist if two values are the same. We can see clearly that two points have the coordinates of (10,6) and (10,9). Because there are two points with 10 as the x coordinate, the relation is not a function.
