Algebra I

• Range is the set of y-values that are outputted by function f(x)

Explanation:

From the graph we see that our y-values span from -4 to 4. When y = -4, it is a open dot, meaning it is exclusive. When y = 4, it is a closed dot, meaning it is inclusive. Therefore, our range is:

(-4, 4] or -4 < y ≤ 4
