Understanding Piecewise Functions

The video tutorial explains how to graph a piecewise function with three linear segments. It covers the process of plotting each segment based on given intervals and calculating specific function values at certain points. The tutorial emphasizes understanding slopes, intervals, and graphing techniques for linear functions.

What is a key characteristic of each piece in the piecewise function discussed?

• Each piece is quadratic.

• Each piece is exponential.

• Each piece is linear.

• Each piece is constant.
