Question

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.

Explanation:

In the function \( f(x) \), \( x \) represents the weight of the wagon (in pounds) and \( f(x) \) represents the force (in newtons). When \( x = 8 \) (weight of the wagon is 8 pounds) and \( f(x)=25 \) (force value), it means for the input \( x = 8 \) (weight), the output \( f(x)=25 \) (force).

Answer:

It takes 25 newtons to accelerate an 8 - pound wagon.
