Hey there! :)

Answer:

D: [-3, 1).

R: [ -8, 1].

Explanation:

Examine the graph. Notice there is a closed and open circle.

Closed circles require the ] bracket to be used, while:

Open circles require the ) bracket. Therefore:

Domain:

The domain is from x = -3 to x = 1. Therefore:

D: [-3, 1).

The range, or y values in this function are from -8 to 1. Therefore:

R: [ -8, 1].

*** The range for this graph can be tricky. Remember, in this instance the highest point of the graph was at x = 0, not at x = 1 where the graph ended.
