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

12

Explanation:

Answer 2

Option A is correct, i.e. 12.

Explanation:

Given is the table of x&y relationship which represents an exponential function.

The average rate of change for a function can be found using the following formula:-

F_average = { f(b) - f(a) } / (b-a)

Given a = 3 and b = 5.

From the table, f(3) = 8 and f(5) = 32.

So, F_average = (32-8)/(5-3)

F_average = 24/2 = 12.

Hence, option A is correct, i.e. 12.
