Interactive Mathematics: Introduction to Functions

Introduce your algebra learners to linear and quadratic functions. Learners compare the differences and relate them back to the equations and graphs. Lead your class to discussions on the properties of a function or a constant slope...

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...

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,...

Functions serve an important function in mathematics. Viewers of an illuminating video learn basic concepts related to functions. They see how to identify independent and dependent variables, write functions to model scenarios, and...

Note the function notation. Learners watch a short video that provides a primer in function notation. They see how to apply function notation for points given as ordered pairs, as a table of values, or as a graph, and how to interpret...

Even algebra beginners can understand even and odd functions. Viewers of a short video learn the definition of even and odd functions. The video investigates y = x^2 and y = x^3 using both algebraic and graphical methods.

An instructional video explaining the concept of function inverses. A linear function is given and a diagram is drawn to show the mapping of some elements of the domain to the corresponding elements in the range. The inverse of the...

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...
