Question

This table shows a value that represents an exponential function what is the average rate of change for this function for the interval from x=3 to x=5?

Answer 1

C. 49

Explanation:

I took the test

Answer 2

C

Explanation:

The average rate of change on an interval is simply the slope between the endpoints.

We want to find the average rate of change of function y from x= 3 to x = 5.

Find the endpoints. From the table, we know that the endpoints are (3, 27) and (5, 125).

The slope between them is:

`\displaystyle m=(125-27)/(5-3)=49`

So, the average rate of change of function y from x = 3 to x = 5 is 49.

Our answer is C.
