Answer:

Yes

Step-by-step explanation:

To be a function, the graph must pass the vertical line test.

The vertical line test is simple. Imagine you draw an infinite number of vertical lines. In all of these lines, it should never hit the function twice in the same x value.

For example, if it hits (4, 2) and (4, 7), the graph is not a function because there are two points with the same x value.
