Question

the graph shows two racers during a race.

1. what is j(3)?______ what does this mean?
2. when does a(x)=4?______ what does this mean?

Explanation:

Step1: Identify the function J(t)

J(t) represents Juan's distance as a function of time.

Step2: Locate t = 3 on the graph

On the x - axis (time), find t = 3.

Step3: Find the corresponding y - value (distance)

For Juan's graph (the one with a flat - spot after t = 5), when t = 3, the y - value (distance) is 1.5 miles.

Answer:

\(J(3)=1.5\). This means that at \(t = 3\) minutes, Juan has run \(1.5\) miles.
