kotykmax [81]

Answer: Second Option

m=0.09

Step-by-step explanation:

The formula for calculating the average rate of change between two values of x (x_1 and x_2) is:

m=\frac{f(x_2)-f(x_1)}{x_2-x_1}

f (x_1) and f (x_2) are the values of the function when x = x_1 and x = x_2

In this case

x_1=3\\x_2=6

Observe that when x=3, f(x) =2.41 and when x=6, f(x)=2.68

Finally the average rate of change from 3 to 6 storms is:

m=\frac{2.68-2.41}{6-3}

m=0.09
