State the range in proper interval notation

Answer:
the range in interval notation is (-4, 4).
Step-by-step explanation:
"Range" refers to the set of numbers that contains all possible values of y that a given function can take on. In this diagram we see that the smallest possible y-value is -4 and the largest is +4, not inclusive (the set does not contain either -4 or +4). Thus, the range in interval notation is (-4, 4).
