Algebra 2: Quadratic Functions and Stopping Distance
by Texas Instruments

Updated on August 15, 2014

#### Objectives

• Students will utilize data in real-life applications of the quadratic function.
• Students will generate quadratic regression equations to model the relationship between two variables in a set of data.
• Students will interpolate and extrapolate values using their quadratic models for this real-life application.
• Students will write compound inequalities to describe the effect of various driving conditions on stopping distance.
• Students will construct viable arguments & critique the reasoning of others (CCSS Mathematical Practice).
• Students will model with mathematics (CCSS Mathematical Practice).

#### Vocabulary

• compound inequality
• extrapolate
• interpolate

This lesson involves analyzing data. As a result, students will:

• Compare stopping distance under normal driving conditions with stopping distance while talking on a cell phone or driving in wet weather.
• Generate quadratic equations to model the effects of different factors such as talking on a cell phone or driving in wet weather on stopping distance and compare it to the stopping distance under normal conditions.
