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

OPTION B

Step-by-step explanation:

As you can see in the graph, when x=1, y=3 and when x=4, y=0

Then, draw a line that cut the points (1,3) and (4,0), as you can see in the image attached, and calculate the slope (which represents the average rate of change of the function), with the following formula:

Therefore, the aswer is the option B.

(1,4) is on graph of f(x)

f(1) = 4

so 1/4 f(x)

1/4 f(1)

1/4. ×4

1

so point for function 1/4. f(x) is (1,1)
