in physics class, the students found that it takes a force of f(x) newtons to accelerate a wagon that weighs x pounds. what does f(8) = 25 tell you? it takes 8 newtons to accelerate a 25 - pound wagon. it takes 25 newtons to accelerate an 8 - pound wagon.
Answer
# Explanation:
## Step1: Understand function notation
The function is $f(x)$ where $x$ is the weight of the wagon in pounds and $f(x)$ is the force in newtons. When $x = 8$ and $f(x)=25$, it means we substitute $x$ with 8 in the function $f(x)$.
## Step2: Interpret the result
$f(8) = 25$ implies that when the weight of the wagon $x$ is 8 pounds, the force $f(x)$ required to accelerate it is 25 newtons.
# Answer:
It takes 25 newtons to accelerate an 8 - pound wagon.
