Overview

The purpose of this lesson is to learn how to apply the properties of quadratic functions to real world problems and interpret the result in the context.

This lesson will address the following CCRS Standard(s) for Functions:

F.IF.4: For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. For example, for a quadratic function modeling a projectile in motion, interpret the intercepts and the vertex of the function in context of the problem. Key features include: intercepts, intervals where the function in increasing, decreasing, positive, or negative, relative maximums and minimums; symmetries; end behavior; and periodicity.
F.BF.1: Write a function that describes a relationship between two quantities

Summary

In this lesson we have learned:

Quadratic functions can model many real world events
If we want a max/min this is the vertex
If we want to "hit the ground" this is the x-intercept
