Exploring Piecewise Linear Functions

This video tutorial covers various mathematical concepts for 8th-grade students. It begins with a call to engage with the content, followed by lessons on piecewise linear functions, comparing outputs of equations and graphs, analyzing a bike trail graph, and solving volume equations for containers. The video concludes with a reminder to like, comment, share, and subscribe.

What does the graph suggest about the car's movement?

• The car moved in a straight line without stopping.

• The car traveled to a location, stopped, and then returned.

• The car was stationary throughout the observed period.

• The car accelerated continuously over time.
