Identifying Increasing and Decreasing Intervals - Quadratic Functions

This document is a "How to Guide" that offers step by step instructions on how to identify increasing and decreasing intervals of polynomial functions. It uses a quadratic example to get students started with the concept of a turning point, what that actually means, and how intervals relate to the domain, x-axis, and a visual of the number line.

This is a great reference for your algebra one, algebra two, and even pre-calc classes!
