Question

Determine which relation is a function.

Answer 1

its not B

Do you know about the vertical line test?

Answer 2

the last one is a function, since the rest of the graphs have multiple y's associated with one same x (the converse is fine)

Answer 3

and we assume that a function is a map that has an inverse, which means you are searching for a function that is some kind of bijection

Answer 4

we do not assume a function has an inverse

example x^2

Answer 5

none of these are bijections
