Question

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

Answer 1

Answer:

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

Step-by-step 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.

The correct answer is C.
