Answer: 9 ≥ y ≥ -9
Explanation:
The range of the function is all possible output values or the y-values in a graph. Here, we see that this graph stays between the y-values of 9 and -9, giving us the range. There are a few different ways to write this, but I will write it in inequality notation.
The range (y) is between the values 9 and -9, so we will write it like this:
9 ≥ y ≥ -9
