Question

What is the average rate of change from x = 1 to x = 3?

−4
−2
2
4

Answer 1

The average rate of change would be 2

Explanation:

To find this, we need to create ordered pairs for the two spots on the graph. These would be (1, -3) and (3, 1). Now we can use the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (1 - -3)/(3 - 1)

m = 4/2

m = 2
