Question

Find the x-intercepts of the function graphed below, and the average rate of change over the interval (-1,4).

x-intercepts:____

Average rate of change:____​

Answer 1

x-intercepts: -2; 1; 5

Average rate of change: 1.8

Explanation:

x- intercepts as per graph are:

• -2; 1; 5

Average rate of change over the interval (-1, 4) is:

• Δy/Δx = (y(4) - y(-1))/(4 - (-1)) = (3 - (-6))/5 = 9/5 = 1.8
