The graph shows the function f(x).

Which value is closest to the average rate of change from x = 1 to x = 4?

a. −3.5
b. −2.3

c. −1.4
d. −0.3

a) -3.5

Step-by-step explanation:

The average rate of change of a function f(x) from x=a to x=b is given by:

We want to find the average rate of change of change of the given function from x=1 to x=4.

From the graph,

The average rate of change is:

a) is closest

3+x
