Khan Academy: Introduction to Functions: Functions Part 2

In this functions worksheet, students solve 70 short answer questions. Students find domain of functions and evaluate them for a given value. Students determine if a mapping diagram represents a function.

In this introduction to functions video, Sal intuitively defines a function and introduces the function notion f(x). He finishes the video by looking at a simple example of evaluating g(f(x)) without getting into the complexity of...

Starting from a brief look at functions and the mapping of domains to ranges, Sal starts with an intuitive sense of what a function inverse is. Using an example, he then shows how to find the inverse of a function and how the graph of...

Sal gets to the heart of this video, clarifying that it's important to understand math "so you can apply it later on and not have to relearn everything every time." True to his word, Sal demonstrates ways to solve logs and exponents more...

Let the video function as a catalyst to study functions. Young mathematicians watch a short video to continue learning about functions. They watch as the narrator completes function tables by evaluating functions for specific values,...

Second part of the introduction to logarithm properties.

This interactive website provides a variety of lesson plans according to which standards you are applying and which textbook you use. Introduce functions to your class by having them construct single operation machines and create...

Video [6:07] showing how to solve for a function given a composition of functions and one of the functions. Also shows how the problem can be solved using the different multiple choice options.

Functions are investigated in this video tutorial.[9:33] Students learn about the algebra concept through detailed examples.
