Intro to Exponential Functions
F.IF.4 Using tables, graphs, and verbal descriptions, interpret the key characteristics of a function which models the relationship between two quantities. Sketch a graph showing key features including: intercepts; interval where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity.
F.IF.5 Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes. For example, if the function h(n) gives the number of person‐hours it takes to assemble n engines in a factory, then the positive integers would be an appropriate domain for the function.
MGSE9‐12.F.IF.7e Graph exponential functions, showing intercepts and end behavior.

Vocabulary: Exponential Function ‐ a function with a constant base and a variable exponent. Example: f(x) = 2x
Asymptote ‐ A value that a function approaches but never reaches. This is represented graphically by a dotted line.
Exponential Growth ‐ An exponential graph that is increasing from left to right. Caused by a base greater than 1. Example: f(x) = 2x
Exponential Decay ‐ An exponential graph that is decreasing from left to right. Caused by a base greater than 0 but less than 1. Example: f(x) = (1/2)x
