Answer:

Explanation:
Domain
Domain is the set of all valid x values for the function
Looking at the graph we see that the function x values go from x- 4 to x = +4.
Note the unfilled circle at x = -4, y = 5. This means that this point is not included in any set of values that we intend tp find. It will represent a < or > inequality.
A filled circle means that value is included
So the domain of the function is -4 < x ≤ 4 (note that -4 is not included in the domain
Range
The range is the set of all y values for the entire domain. Basically it is defined using the min and max values that y can take
The minimum y value occurs at x = 4 and y is -2 (this is included because of the filled circle)
The max value occurs at x = -4 and the value of y here is 5 (5 is not included)
Therefore the range is -2 ≤ y < 5
