Question

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

Answer 1

Explanation:

honestly, it's most likely a function. I know it's a function, but I don't understand what not one-to-one means, so, I guess it's just a function and nothing else?

Answer 2

Linear Function

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.
