: Is the relation a function? If so, is it one-to-one or not one-to-one?

Answer:
Linear Function
Step-by-step explanation:
Ok, so this is a function. This is because none of the X's repeat with a different Y. "Every Input has EXACTLY one Output"
BUT: I don't know what a One-to-one is. I would guess it means linear, which means it's a straight line on a graph. If that's the case, then it would be infact a Linear Function.
