3 Exponential Chapter and Logarithmic Functions Course Number Instructor Section 3.1 Exponential Functions and Their Graphs Objective: In this lesson you learned how to recognize, evaluate, and graph exponential functions. Date Important Vocabulary Define each term or concept. Algebraic functions Functions of x that can be expressed as a finite number of sums, differences, multiples, quotients, powers, and roots. Transcendental functions Functions that are not algebraic. Natural base e The irrational number e 2.71828 . . . I. Exponential Functions (Page 216) The exponential function f with base a is denoted by f(x) = ax number. Example 1: Use a calculator to evaluate the expression 5 3 / 5 . 2.626527804 , where a > 0, a 1, and x is any real What you should learn How to recognize and evaluate exponential functions with base a II. Graphs of Exponential Functions (Pages 217-219) For a > 1, is the graph of y = a x increasing or decreasing over its domain? Increasing What you should learn How to graph exponential functions For a > 1, is the graph of y = a - x increasing or decreasing over its domain? Decreasing 5 For the graph of y = a x or y = a - x , a > 1, the domain is (- , ) the intercept is the x-axis , the range is (0, 1) (0, ) , and y 3 . Also, both graphs have as a horizontal asymptote. -5 -3 1 -1 -1 1 3 5 x Example 2: Sketch the graph of the function f ( x) = 3 - x . -3 -5 Larson/Hostetler/Edwards Precalculus: and Functions Graphs, A Graphing Approach, 3rd Edition Student Success Organizer IAE Copyright Houghton Mifflin Company.

The Natural Base e (Pages 220-221) Chapter 3 Exponential and Logarithmic Functions The natural exponential function is given by the function . f(x) = ex Example 3: Use a calculator to evaluate the expression e 3 / 5 . 1.8221188 For the graph of f ( x) = e x , the domain is the range is (0, ) (- , ) (0, 1) , . What you should learn How to recognize, evaluate, and graph exponential functions with base e , and the intercept is The number e can be approximated by the expression (1 + 1/x)x for large values of x. IV. Compound Interest and Other Applications (Pages 222-224) After t years, the balance A in an account with principal P and annual interest rate r (in decimal form) is given by the formulas: Fo...
