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

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.

1/3

step-by-step explanation:

to find this, you can divide 12 by 4 which is 3 or you can multiply 4 until you reach 12 (4x3=12). both should give you 3, meaning theres three times less bananas than there are oranges.
