Answer:

Step-by-step explanation:

f(x) = x - 2

f(-1) = x - 2       3      -1      3

f(0) = x - 2        2      0     2

f(4.5) = x - 2    2.5   4.5   2.5

Domain is x ≥ 0

The function f(t)=-16 + 100 models the height of a ball, in feet, dropped from a 100-foot rooftop at time t, in seconds.
Mazyrski [523]

Using it's concept, it is found that the average rate of change of the function during the interval from 0 to 2 seconds is given by:

B. -32 ft/s; the average change in altitude of the ball each second over that interval.

<h3>What is the average rate of change of a function?</h3>

The average rate of change of a function is given by the change in the output divided by the change in the input. Hence, over an interval [a,b], the rate is given as follows:

r = \frac{f(b) - f(a)}{b - a}

In this problem, the function is given by:

f(t) = -16t² + 100.

The outputs are given as follows:

  • f(0) = -16(0)² + 100 = 100.
  • f(0) = -16(2)² + 100 = 36.

Hence the average rate of change is given by:

r = (36 - 100)/(2 - 0) = -32 ft/s.

And the correct option is:

B. -32 ft/s; the average change in altitude of the ball each second over that interval.
