A function is defined as a set of points for every x-value, there is only one y-value.
So, you can't have two y-values for every x-value.

Thus, (B) would be a relation, because x = 7 has two y-values, and as such, doesn't satisfy the condition of a function.

The answer is B.

Negative numbers are to the far left if you were using a number line, so -1 to the 3rd power is -1. Everything else is positive. 1/4 is the same as 0.25 which is less than positive 1, positive 8.8 is next and the last would be -5 to the 2nd power which is 25.
