Question

Use the graph to determine the domain and range of the relation and wether the relation is a function

Answer 1

C. Domain: {
`x|-8\le x\le8`}, Range: all real numbers;No, it is not a function

Explanation:

From the diagram in the attachment, the domain is {
`x|-8\le x\le8`}.

The reason is that, the furthest the graph could extend is 8 to the right and left of the y-axis.

The range of the relation is all real numbers. The reason is that, the graph extends up above and below the x-axis without bounds.

The relation is not a function, because its graph failed the vertical line test.

See graph

The correct answer is C.
