60°, 120° and 180° are the angles at which it will map onto itself.
The answer to this is A and D. A and D are both rational because they contain repeating numbers.
B) could've been the answer but it doesn't show any repeating numbers
C) Doesn't have a repeating number.
So A and D are the answers. (if there is only one option for this answer then D should be the answer)

Answer:
NOT a function!
Step-by-step explanation:
A function is a relation where each input has only one and ONLY one output. For example, for the number 2 in a relation, that number 2 can only have one other y value it is paired with, it can not have more than one.
For example, in this problem the number 2 is stated twice. One set has (2, -8) and (2, 8), so that means this input has more than one output. Therefore, this relation is NOT a function.
