Question B: During what interval(s) of the domain is the baseball’s height decreasing the fastest?

Options: A= 6 < x < 8; the slop is the steepest for this interval

B= 8 < x < 10; the slop is the steepest for this interval

C= 6 < x < 10; the slop is decreasing for this interval

D= 6 < x < 12; is where the slope is decreasing

Answer 1

Explanation:

it decreases the fastest, where it drops the most feet in the same period of time.

the dots are made in 2 seconds intervals.

between the seconds 6 and 8 the ball drops from 65 ft to 25 ft (a drop of 65 - 25 = 40 ft).

bergen the seconds 8 and 10 the ball drops from 25 ft to 5 ft (a drop of 25 - 5 = 20 ft).

and then between the seconds 10 and 12 the ball drops from 5 ft to 0 ft (a drop of 5 ft).

so, A is the right answer. with 40 ft in 2 seconds the ball is dropping the most (= the fastest) between the seconds 6 and 8. which means the slope is negatively the steepest there = the height is decreasing the fastest.
