Exponential Growth Functions. If a quantity increases by the same proportion . r. in each unit of time, then the quantity displays exponential growth and can be modeled by the . equation. Where. C = initial amount. 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. ?. Chapter 1.3. The Exponential Function. DEFINITION:. Let a be a positive real number other than 1. The function. is the . exponential function with base a. ..  . 2. The Exponential Function. The domain of an exponential function is . Appreciation & depreciation. 8. What you Should Learn. I can interpret coefficients and exponents in the context of the problem.. I can model and solve growth (appreciation) and decay (depreciation) problems.. RULE-. Exponential Growth. Modeling Exponential Growth . In 1998, a certain town had a population of about 13,000 people. Since 1998, the population has increased about 1.4% a year..

Exponential Growth & Decay . Standard Form:. y = a•b. x. However, depending on the question, we have to change the growth factor. . 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. . 3.2 Exponential growth and decay: Constant percentage rates. 1.
