Answer:

Step-by-step explanation:

f(1)=2^1+3=2+3=5

f(5)=2^5+3=32+3=35

[tex]rate ~of~change=\frac{f(5)-f(1)}{5-1} =\frac{35-5}{5-1} =\frac{30}{4} =7.5[/tex]

Answer:

15/2

Step-by-step explanation:

To find the average rate of change

f(5) - f(1)

-----------------

5-1

f(5) = 2^5 +3  =32+3 = 35

f(1) = 2^1 +3 =2+3 =5

35 - 5

-----------------

5-1

30

------

4

15/2

The average rate of change is 15/2
