The video tutorial covers piecewise functions, including graphing techniques and domain/range analysis. It explores quadratic and linear functions within piecewise contexts and delves into function composition with practical examples. The session concludes with details on homework assignments and due dates.

What is a piecewise function?

• A function that is always continuous.

• A function that has no domain restrictions.

• A function defined by multiple equations over different intervals.

• A function defined by a single equation.
