Question

Hey help me with this question plzzzz

Answer 1

Two Answers: choice C, choice D

Look at where we don't have repeating x values. This happens with function C and function D. All the x values are unique for each choice mentioned.

In choices A, B, and E, the value x = -3 repeats itself. So we don't have a function for either of these. A function is only possible if any input (x) leads to exactly one output (y).

Answer 2

The answer is c and d
