Question

Answer using set notation if possible.

What is the domain?

What is the range?

Is this the graph of a function? Justify with evidence from the graph.

Answer 1

Domain:

[-5,-2) U (-2,3.5) U (3.5,5]

Range:

[-3 0) U (0,5]

It is not a function because x = 1 has two different outputs (3 & 5)
