Question

Use the graph below to answer the following question:

What is the average rate of change from x = –4 to x = 1?

–3
–1
0
1

Answer 1

To find average rate of change, calculate rise (change in y) over run (change in x)
5/5=1
Final answer:1

Answer 2

the values of f(x) at x = -4 and x = 1 are 4 and -1 respectively.

average rate of change =   (-1 - 4) / 1 - (-4) = -5 / 5 = -1
