Answer:

D, the horizontal line is a function

Explanation:

To pass the vertical line test, a vertical line cannot go through the function more than once

A is a vertical line so it will fail the vertical line test

B will fail the vertical line test at many points. One example is at

x =0 where you can see it will intersect at two points

C will fail the vertical line test at many points. One example is at

x =0 where you can see it will intersect at two points

D is a horizontal line. This will pass the vertical line test
