Question

isaiah works as a groundskeeper at a racetrack, where he is part of a bigger crew. when x people are working on the crew, it takes them f(x) hours to get the track ready for a day of racing.
what does f(8) = 4 tell you?
when there are 8 people working on the crew, it takes 4 hours to ready the track.
when there are 4 people working on the crew, it takes 8 hours to ready the track.

Explanation:

The function \( f(x) \) is defined as the number of hours it takes \( x \) people to get the track ready. So \( f(8) = 4 \) means when \( x = 8 \) (8 people working), the time \( f(x) \) is 4 hours. The first option correctly interprets this, while the second swaps the input and output values.

Answer:

When there are 8 people working on the crew, it takes 4 hours to ready the track.
