The path of a baseball thrown at an angle of 40 degrees can be modeled by y=-0.05x^2+3.2x+8y=−0.05x 2 +3.2x+8 where x is the horizontal distance in feet from the release point and y is the corresponding height, in feet. Calculate the average rate of change of the height over the interval 8\le x\le208≤x≤20.

The average rate of change of the height

Step-by-step explanation:

The average rate of change of a function is given by:

Where:

f(x) is the funtion, in our case

f(b) is the function evaluated in b, when b = 20

f(a) is the funtion evaluated in a, when a = 8

Let's find f(a) and f(b):

Therefore, using the average rate of change equation.
