Exponential Functions (Percent Increase or Decrease) Guided Notes and Practice
This assignment covers word problems about exponential functions with percent increase or decrease. For example, if there are 5000 people in your town, and the population grows by 10% per year, how many people are in your town in 8 years? This worksheet has a QR code, which links to a video that walks students through the "guided notes" portion of the assignment, which they can follow with 8 individual practice problems.

Increasing, Decreasing, Domain, Range, Function Values Graph
It is hard to find graphs for students to be able to identify where a function is increasing, decreasing, constant, domain, range, maximums, minimums, and function values. I have worked really hard over the years to create my own graph to use as practice or even a quiz on these topics.

Library of Functions Quiz
I have created a wonderful quiz on the library of functions. I have used Cubic function, Absolute value function, Identity function, Square root function, Square function, and Reciprocal function. Students must match the graph, name, domain, range, increasing, decreasing for each function. This quiz is a great tool for assessing your students understanding of the characteristics for each function.

Linear vs. Exponential
Sometimes students just need to practice writing equations. Here is a worksheet that allows the students to write linear equations and exponential equations from tables. They then have to decide if the function is linear or exponential and increasing or decreasing. I created this worksheet 5 years ago and every year I hear students say, "Oh, that's the difference." It doesn't take long and makes a great worksheet for after a quiz or as a homework assignment.

From bacteria to bank accounts—students build, interpret, and reverse-engineer exponential models from real-world contexts using a structured four-part process they can apply to any scenario. This lesson bridges exponential function skills to real-world application using four model types: direct multipliers (doubling, tripling, halving), percent increase, percent decrease, and reverse engineering from tables and graphs. Every example follows the same four-part format—identify components, write t
