# Lesson Plan: Increasing and Decreasing Intervals of a Function Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find the intervals over which a function is increasing, constant, or decreasing.

#### Objectives

Students will be able to

• recall the condition for a function to be increasing, decreasing, or constant over the interval ,
• identify the increasing and decreasing intervals of a simple function from its equation,
• identify the increasing and decreasing intervals of a function from its graph,
• give conditions for which a given equation is increasing or decreasing.

#### Prerequisites

Students should already be familiar with

• the domain and range of a function,
• graphs of various types of functions.

#### Exclusions

Students will not cover

• differentiation.
