Mr. Wilkinson'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)After 8 seconds, the rocket has already landed on the field. (B)The rocket starts its launch 8 feet above the ground.

Understand function and variables: Understand the function and variables. The function f(x) represents the rocket's height in feet at x seconds after launch. The variable x represents the number of seconds elapsed since the rocket was launched.Interpret given function value: Interpret the given function value. The function value f(8) = 0 means that at 8 seconds after the rocket was launched, its height above the ground is 0 feet.Choose correct interpretation: Choose the correct interpretation based on the function value. Since f(8) = 0 indicates the height is 0 feet at 8 seconds, it tells us that the rocket has returned to the ground after 8 seconds. Therefore, the correct choice is: (A) After 8 seconds, the rocket has already landed on the field.

Q. Mr. Wilkinson'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)After

8

seconds, the rocket has already landed on the field.

\newline

(B)The rocket starts its launch

8

feet above the ground.

Understand function and variables: Understand the function and variables. $\newline$ The function $f(x)$ represents the rocket's height in feet at $x$ seconds after launch. The variable $x$ represents the number of seconds elapsed since the rocket was launched.
Interpret given function value: Interpret the given function value. $\newline$ The function value $f(8) = 0$ means that at $8$ seconds after the rocket was launched, its height above the ground is $0$ feet.
Choose correct interpretation: Choose the correct interpretation based on the function value. $\newline$ Since $f(8) = 0$ indicates the height is $0$ feet at $8$ seconds, it tells us that the rocket has returned to the ground after $8$ seconds. Therefore, the correct choice is: $\newline$ (A) After $8$ seconds, the rocket has already landed on the field.
