Lesson 3a – Introduction to Exponential Functions Assessment 3. One 12-oz can of Dr. Pepper contains about 39.4 mg of caffeine. The function A(x) = 39.4(0.8341) x gives amount of caffeine remaining in the body x hours after drinking a can of Dr. Pepper. Answer in complete sentences. a) Determine the half-life of caffeine in the body (i.e. How long will it take the body to metabolize half of the caffeine from one can Dr. Pepper?). Show all of your work and write your answer in a complete sentence. Round your answer to two decimal places as needed. b) How much caffeine is in the body eight hours after drinking the Dr. Pepper? Show all of your work and write your answer in a complete sentence. Round your answer to two decimal places as needed. c) How much caffeine is in the body one day after drinking the Dr. Pepper? Show all of your work and write your answer in a complete sentence. Round your answer to two decimal places as needed. d) According to this model, how long will it take for all of the caffeine to leave the body?

Lesson 3b – More Exponential Functions Now that we have studied the basics of Exponential Functions, it is time to look at several specific concepts. In this lesson, we study Exponential Growth and Exponential Decay and look at ways to model and measure each. We also learn how to use our calculator to create an Exponential Model by using the Linear Regression tool. Lesson Objectives: 1. Write EXPONENTIAL GROWTH MODELS 2. Determine DOUBLING TIME 3. Write EXPONENTIAL DECAY MODELS 4. Determine HALVING TIME 5. Use EXPONENTIAL REGRESSION to write exponential growth or decay models Scottsdale Community College Page 121 Intermediate Algebra
