#3 find domain and range using interval notation

Hey there! :)
Answer:
D : [-4, ∞)
R: [-2, ∞)
Step-by-step explanation:
Notice that one end of the graphed function has a closed circle, and one end is a line. We must use specific brackets accordingly:
[ is used for closed points.
( is used for arrows or open circles.
Therefore:
This graph goes from x = -4 towards x ⇒∞. Therefore:
D : [-4, ∞)
The range of this function goes from x = -2 towards y⇒ ∞. Therefore:
R: [-2, ∞)
