This course requires very little math – just a small number of fairly simple formulas. One math concept we’ll need (for the decibel scale, later) is . exponential notation.. It’s not hard, and you’ve already had it.. Exponential Function. f(x) = a. x. . for any positive number . a. other than one.. Examples. What are the domain and range of. . y = 2(3. x. ) – 4?. What are the. roots of . 0 =5 – 2.5. x. ?. Reva . Narasimhan. Associate Professor of Mathematics . Kean University, . NJ. www.mymathspace.net/presentations. Overview. Introduction . Why functions?. Challenges in teaching . the function concept. Exponential Functions & Their Graphs. Logarithmic Functions & Their Graphs. Properties of Logarithms . Exponential and Logarithmic Equations. Exponential and Logarithmic Models. a. b.. Write equivalent forms for exponential and logarithmic functions.. Write. , evaluate, and graph logarithmic functions.. . Objectives. logarithm. common logarithm. logarithmic function. Vocabulary. Why are we. Section 6.3 Beginning on page 310. Logarithms. For what value of x does . ? Logarithms can answer this question.

Use calculators to calculate graphing points. f(x) = 3x – 1. 2. . 3. f(x) = 2. x. Logarithms. If f(x) = a. x. is a proper exponential function, . then the inverse of f(x), denoted by f. -1. (x), . is given by f. -1 . (x) = . log. a. x. . Exponential Growth. Exponential growth. occurs when an quantity increases by the same rate . r. in each period . t. . When this happens, the value of the quantity at any given time can be calculated as a function of the rate and the original amount. . Differentiate between linear and exponential functions.. 4. 3. 2. 1. 0. In addition to level 3, students make connections to other content areas and/or contextual situations outside of math..  . Students will construct, compare, and interpret linear and exponential function models and solve problems in context with each model.. The . inverse . of a relation is the set of ordered pairs obtained by . switching the input with the output. of each ordered pair in the original relation. (The domain of the original is the range of the inverse; and vice versa). All slides in this presentations are based on the book Functions, Data and Models, S.P. Gordon and F. S Gordon. ISBN 978-0-88385-767-0. Fitting Data to An Exponential Function. Although Linear Regression is a powerful tool, not all relationships between two quantities are linear.
