Describe how to determine the average rate of change between x = 4 and x = 6 for the function f(x) = 2x3 + 4. Include the average rate of change in your answer.

Average rate of change for function is 152 between x=4 and x=6

Step-by-step explanation:

We need to find average rate of change for function between x=4 and x=6

The formula used to determine the average rate of change is

Where b=6 and a=4

Finding f(a) and f(b)

Finding f(b)

Putting values in formula:

So, average rate of change for function is 152 between x=4 and x=6

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile
