INFORMATION:
We have a graph and we must determine if it is a function using the vertical line test
STEP BY STEP EXPLANATION:
To determine it, we need to know that the vertical line test is a visual way to determine if a curve is a graph of a function or not.
If all vertical lines intersect a curve at most once then the curve represents a function.
Now, applying the vertical line test to our graph
We can see that all vertical lines intersect the graph at most once, so y is a function of x
ANSWER:
Yes
