College Math Lesson 6.4 - Representing Functions

Objective: At the end of this lesson, students will be able to represent a function in three different ways and describe the domain and range of a function Three Basic Ways to Represent a Function Vocabulary: Domain – Range – Example: The following table shows typical values you might find for atmospheric pressure at different altitudes, with the pressure given in units of inches of mercury. Graph the function represented in the table, describe its domain and range, and use the function to predict the atmospheric pressure at an altitude of 15,000 feet. Altitude (feet) Pressure (inches of mercury) 0 30 5,000 25 10,000 21 20,000 14 30,000 9
