Question

Which representation does NOT show Y as a function of X?

Answer 1

Answer:

D

Step-by-step explanation:

A function is valid if each x input has a different y counterpart

In picture D both 3 and 5 repeat --> (3,2)(2,6) and (5,6)(5,8)

This would create an undefined line that would fail the vertical line test (multiple x values on one y value)
