Answer:

Using the vertical line test, the functions are b, c, d, and f

Step-by-step explanation:

a and e both fail the vertical line test, therefore, it's not a functions.

B, c, d, and f are functions because they pass the vertical line test. If you were to draw a straight line down the graph, the points would only touch the line once. A and E however, touch the line two or more times.
