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

Gaps have no data in them. So the range 1-2 is a gap.
Clusters are groups of data that are right next to each other.
So the range 3-6 on your dot plot is a cluster, because there is a group of data there with no gaps.
Peaks are the greatest amount of data in the dot plot. 0 and 5 are the peaks because they both have the most data, 4.
Y-585 = -7.5(x-15)
y = -7.5x - 7.5(-15) + 585
y = -7.5x + 697.50
C = -7.5(52) + 697.50 = $307.50
