Increasing, decreasing constant intervals

The video tutorial explains how to determine if a function is increasing, decreasing, or constant by analyzing graphs and equations. It provides three examples: a basic graph, a polynomial function, and a piecewise function. The tutorial emphasizes the importance of using X values to describe intervals and demonstrates how to identify these intervals using graphing tools like Desmos. The video aims to help viewers understand the differences in function behavior and how to describe them accurately.

What are the intervals of increase and decrease for the polynomial function discussed?

How does a piecewise function differ from a standard function in terms of intervals?

Summarize the key points about describing constant intervals when given an equation.
