Question

Use the graph below to answer the following question:

what is the average rate of change from X=1 to X=4

A -3
B -1
C 1
D 3

Answer 1

9514 1404 393

Answer:

  B.  -1

Step-by-step explanation:

The relevant points on the graph are (1, 3) and (4, 0). The average rate of change can be found using the slope formula ...

  m = (y2 -y1)/(x2 -x1)

  m = (0 -3)/(4 -1) = -3/3 = -1

The average rate of change from x = 1 to x = 4 is -1.
