If you would like to download just one of these files, contact me and I'll set up a listing for you. A single file is $1.
This file includes 11 resource files for an introduction to exponential functions:
- Evaluating Exponential Expressions
- Graphing Exponential Functions
- Exponential Growth and Decay
You will download a .zip file from which 11 .doc files can be extracted.
Each file includes a key for the notes and practice problems. The files include guided notes, homework, and two mini-activities. See descriptions below:
1 - Population Growth Intro Activity: Students compare and contrast linear and exponential functions through graphing and verbal descriptions.
2a - Exponents Review: A review of exponents, including negative exponents.
2b - Evaluating Exponentials: Practice evaluating exponential expressions.
3 - Graphing Exponentials: Guided notes and practice for graphing exponential functions, including those with vertical shifts.
Note: I teach graphing differently than a lot of teachers; the answer key to this file gives a detailed description of my method.
Note: File #3 can be downloaded on its own for $1 at
4 - Writing Equations: Guided notes and practice writing equations of exponential functions based on verbal descriptions, tables, and graphs.
5a - Exponential Growth Notes: Guided notes for exponential growth.
5b - Exponential Growth HW: Practice homework about exponential growth.
6a - Exponential Decay Notes: Guided notes for exponential decay.
6b - Exponential Decay HW: Practice homework about exponential decay.
7 - Exponential Decay Activity: Students drop M&Ms and record (and remove) the number that land "M-up," creating an exponential decay function.
8 - Exponential Growth and Decay Summary and Practice: Summary and mixed practice with exponential growth and decay problems.
Common Core Standards:
A-CED.1 Create equations in one variable and use them to solve problems. Include equations arising from exponential functions.
F-IF.7e Graph exponential functions.
F-IF.8b Use the properties of exponents to interpret expressions for exponential functions.
F-LE.2 Construct exponential functions given a graph, a description of a relationship, or two input-output pairs (include reading these from a table)
F-LE.5 Interpret the parameters in an exponential function in terms of a context
S-ID.6 Fit a function to the data; use functions fitted to data to solve problems in the context of the data.
