Question

I'LL MARK BRAINLIEST!! PLEASE HELP ASAP! 21 POINTS!

The graph below shows the height of a kicked soccer ball f(x), in feet, depending on the distance from the kicker x, in feet:

Graph of quadratic function f of x having x-intercepts at ordered pairs 0, 0 and 16, 0. The vertex is at 8, 10. (The graph is down below!)

Part A: What do the x-intercepts and maximum value of the graph represent? What are the intervals where the function is increasing and decreasing, and what do they represent about the distance and height?

Part B: What is an approximate average rate of change of the graph from x = 8 to x = 13, and what does this rate represent?

Answer 1

Answer:

pls mark me as brainliest if you are satisfied

Step-by-step explanation:

a.

x=0 gives the original position of the ball

x=16 gives the distance covered by ball before it comes back to the ground.

y=10 gives  the maximum height the ball attains.

b.

average rate of change

=f(13)−f(8)13−8

=7.5−1013−8

=−2.55

=−0.5
