Record any similarities or differences between them. CONNECT WITH US. Introduction to Exponential Functions (Day 1, Exponential Functions) In this handout, we will introduce exponential functions. In words, to divide two numbers in exponential form (with the same base) , we subtract their exponents. Rule 2: bn bm = b n−m. Some Examples of Exponential Functions: Definition We say f (x) is an exponential function if f (x) = abx where a≠0, b>0, and b≠1. The figure on the left shows exponential growth while the figure on the right shows exponential decay. Exponential generating functions are of another kind and are useful for solving problems to which ordinary generating functions … Introduction to Exponential Generating Functions. 11. Introduction to Exponential Functions Again, exponential functions are very useful in life, especially in the worlds of business and science. If you’ve ever earned interest in the bank (or even if you haven’t), you’ve probably heard of “compounding”, “appreciation”, or “depreciation”; these have to do with exponential functions. 5472 Park Place. Compare the graphs. We have seen several applications of generating functions – more specifically, of ordinary generating functions. Create a table of values AND graph each of the following functions on the same set of axes. Algebra Writing Exponential Functions From Tables Practice Riddle Worksheet This is an 15 question Riddle Practice Worksheet designed to practice and reinforce the concept of writing an exponential function f(x) given a table. (Use x = -2, -1, 0, 1, 2). As you can see from the figure above, the graph of an exponential function can either show a growth or a decay. a) y = 2x b) y = 3x c) y = 4x 2. SOLUTIONS TO EXPONENTIAL FUNCTIONS AND EQUATIONS EXTRA PRACTICE. We have not yet given any meaning to negative exponents, so n must be greater than m for this rule to make sense. Mathematics Learning Centre, University of Sydney 2 This leads us to another general rule. EXPONENTIAL FUNCTIONS (INTRODUCTION) Page 1/3 MBF 3C – Worksheet 1. Lesson 5 – Introduction to Exponential Functions Mini-Lesson Page 178 Section 5.2 – Characteristics of Exponential Functions Exponential Functions are of the form f(x) = abx where a = the INITIAL VALUE b = the base (b > 0 and b ≠ 1); also called the GROWTH or DECAY FACTOR Important Characteristics of the EXPONENTIAL FUNCTION f(x) = abx
