Question

C) ((0, 1), (2, 1), (0,3)}
Function?
Explain:

Answer 1

No.

Explanation:

The function would be a discrete function if the individual points in the function didn't share the same x-coordinates. Both the points (0,1) and (0,3) share the same x-coordinate, x=0, so the function doesn't pass the vertical line test.
