Answer:

Domain:
[-2,1)

Range:
[0,4]

Explanation:

Domain

We can see that the piecewise function starts at x=-2, which is included, and ends at x=1, which isn't included. To represent the x-values that lie in between these two endpoints, you would write
[-2,1). Brackets show that one endpoint is included while parentheses show that one endpoint isn't included.

Range

Following this logic, the range has its y-values go from 0 to 4 with both endpoints included if you were to trace the function. Thus, your range would be
[0,4].
