The graph shows the distance of a car from home as a function of time.

Describe what a person watching the car would see.

The equation \(y=4 \) and the graph shown here represent two functions. Use the equation and the graph to answer the questions.

1. When \(x\) is 4, is the output of the equation or the graph greater?
2. What value for \(x\) produces the same output in both the graph and the equation?

This graph shows a trip on a bike trail. The trail has markers every 0.5 kilometer showing the distance from the beginning of the trail.

Coordinate plane, x, time in hours, 0 to 3 point 4 by point 2, y, distance from beginning in kilometers, 0 to 10 by 2. Line segments connecting the origin and (point 8 comma 8), (1 point 4 comma 8), (2 point 2 comma 10), (2 point 4 comma 10), (2 point 6 comma 5), (3 comma 0).

1. When was the bike rider going the fastest?

2. When was the bike rider going the slowest?

3. During what times was the rider going away from the beginning of the trail?

4. During what times was the rider going back toward the beginning of the trail?

5. During what times did the rider stop?

The expression \(\text-25t+1250\) represents the volume of liquid, in liters, of a container after \(t\) seconds. The expression \(50t+250\) represents the volume of liquid, in liters, of a container after \(t\) seconds.

What does the equation \(\text-25t+1250=50t+250\) mean in this situation?
