True or false

Answer 3

Can a function have different outputs for the same input? Asked another way, can a function have different y values for a certain x value?

Answer 4

Um yes?

Answer 5

Remember your earlier problem regarding x, y pairs? By definition, a function must output the same value every time it is given the same input. Does the relation in the graph give only a single output (y) for all input values (x's)?

Answer 6

No?

Answer 7

Correct.

Answer 8

You can quickly check if the graph of a relation is a function or not by imagining a vertical line on it. If the graph of the relation ever crosses that line twice, it is not a function.
