Mr. Kirby's physics class went to the football field to launch a rocket into the air. The rocket's height in feet, f(x), depends on the number of seconds, x, that have elapsed since launch. What does f(8) = 0 tell you? Choices: (A)The rocket starts its launch 8 feet above the ground. (B)After 8 seconds, the rocket has already landed on the field.

Rocket Height at 8 Seconds: In the context of the problem, f(x) represents the height of the rocket at a given time x seconds after launch. The equation f(8) = 0 means that at x = 8 seconds, the height of the rocket is 0 feet.Rocket Landing Conclusion: Since the height of the rocket is 0 feet at 8 seconds, this indicates that the rocket has returned to the ground after being launched. Therefore, the correct choice is (B) After 8 seconds, the rocket has already landed on the field.

Q. Mr. Kirby's physics class went to the football field to launch a rocket into the air. The rocket's height in feet,

f(x)

, depends on the number of seconds,

x

, that have elapsed since launch.

\newline

What does

f(8) = 0

tell you?

\newline

Choices:

\newline

(A)The rocket starts its launch

8

feet above the ground.

\newline

(B)After

8

seconds, the rocket has already landed on the field.

Rocket Height at $8$ Seconds: In the context of the problem, $f(x)$ represents the height of the rocket at a given time $x$ seconds after launch. The equation $f(8) = 0$ means that at $x = 8$ seconds, the height of the rocket is $0$ feet.
Rocket Landing Conclusion: Since the height of the rocket is $0$ feet at $8$ seconds, this indicates that the rocket has returned to the ground after being launched. Therefore, the correct choice is (B) After $8$ seconds, the rocket has already landed on the field.
