Question

evaluate & interp
the graph shows two racers during a race.

1. what is j(3)?

what does this mean?

1. when does a(x) = 4? what does this mean?

Explanation:

Step1: Analyze the graph for \(A(x) = 4\)

Look at the line representing Antonio (labeled \(A\)). Find the \(x\) - value (time in minutes) when the \(y\) - value (distance in miles) is \(4\).

Step2: Locate the point on the graph

On Antonio's graph, when \(y = 4\) (distance \(4\) miles), the corresponding \(x\) - value (time) is \(15\) minutes.

Answer:

When \(A(x)=4\), \(x = 15\). This means that Antonio has run \(4\) miles after \(15\) minutes.
