Question

Find the domain and range of the function graphed below

Answer 1

Domain:
`[-1,3)`

Range:
`(-5,4]`

Explanation:

Domain is all the x-values, so starting with x=-1 which is included, we keep going to the left until we hit x=3 where it is not included, so we get [-1,3) as our domain.

Range is all the y-values, so starting with y=-5 which is not included, we keep going up until we hit y=4 where it is included, so we get (-5,4] as our range.
