Question

Which statement is true about the relation shown on the graph below?

A)It is not a function because an input has more than one output.

B)It is a function because each output has exactly one input.

C)It is a function because each input has exactly one output.

D)It is not a function because an output has more than one input.

Answer 1

A. It is not a function because an input has more than one output

Explanation:

Every point on the graphed relation besides (0, 0) has more than one output for each input.

Any relation that results in multiple outputs for one input is not a function.

Another way to test if a relation is a function or not is to use the vertical line test, in which you draw a vertical line through the graphed relation and if the vertical line intersects the graph at 2 or more points, the graphed relation is not a function.

Answer 2

b should be the correct one
