#2 find domain and range using interval notation

Hey there! :)
Answer:
D: [-3, 1).
R: [ -8, 1].
Step-by-step 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.
