Evaluating Functions Graphically and Algebraically

Analyze functions by decomposing complex functions and composing simple functions. Through a detailed lesson plan, pupils learn the vocabulary and notation related to the composition of functions. Practice includes both evaluating and...

Notation in mathematics can be intimidating. Use this lesson to expose pupils to the various ways of representing a function and the accompanying notation. The material also addresses the importance of including a domain if necessary....

What do you get when you cross piecewise functions with transformations?  An engaging lesson! The conclusion of a four-part series on the transformations of functions asks class members to apply transformations to piecewise...

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 draws a graphical representation of a function, f(x), and builds and evaluates other functions based on that 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...

This lesson describes how to plug a function into an expression for every x appearance in order to evaluate a function for an algebraic expression. It is 7 of 10 in the series titled "Evaluating a Function for an Algebraic Expression."

This lesson describes how to plug a function into an expression for every x appearance in order to evaluate a function for an algebraic expression. It is 8 of 10 in the series titled "Evaluating a Function for an Algebraic Expression."

This video tutorial does not include narration, but great math music. It describes how to evaluate a function for a variable through example, and procedure. This would be a great clip to assign as homework for learners just beginning to...

Pupils draw the graph of a door opening and closing over time. They graph a given function on their calculators, create a table of values and interpret the results by telling if the door is opening or closing and evaluate the average...
