Using the exponential function 2x + 3, what is the average rate of change between the values 1 ≤ x ≤ 5?

explain answer step by step

7.5

Step-by-step explanation:

The given exponential function is

The average rate of change over a≤x≤b is given by;

This implies that the average rate of change between the values 1 ≤ x ≤ 5 is

We evaluate to get:
