In this algebra functions instructional activity, students review the definition of a function and the four different ways to represent a function. Students then determine if the four given examples represent functions. Students explain their answers.
For this algebra functions worksheet, students complete a table of x and y number pairs. Students then answer the three questions that follow.
Your young algebra engineers brainstorm a list of machines that are then related to algebra functions to begin their exploration of the mighty invention called function notation. A discussion follows using a box to represent the machine (which is named F) that takes in the raw material and alters it. The young engineers are then catapulted into an activity to soar higher in their understanding of a function. When they land, they are able to model a situation using function notation, evaluate function values given domain inputs, interpret the meaning of a function value in context, and leap tall buildings in a single bound.
Sal draws a graphical representation of a function, f(x), and builds and evaluates other functions based that function.
This video continues to look at evaluating functions by looking at examples of evaluating basic composite functions.
In this introduction to functions video, Sal gives an intuitive definition of what a function is 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 much of the complexity of composite functions.
Students graph polynomials functions and analyze the end behavior. In this algebra lesson plan, student differentiate between the different polynomials based on the exponents. They use a TI to help with the graphing.
In this algebra instructional activity, 6th graders review different ways to represent a function. They tell whether a function is represented in the first 2 questions, use rules to complete 6 function tables, and complete 1 word problem.
Learners write the percent of 8 numbers as a ratio. They write 12 percentage problems as decimals and utilize algebra functions to solve 3 equations. Pupils answer two test prep questions involving percentages.
In this addition worksheet, students add upward 15 2 and 3-digit whole numbers problems. Students complete 3 tables utilizing Algebra functions and answer 2 test prep questions.
In this algebraic functions worksheet, learners write a function to determine the relationship between people and barrels of oil used. They research the population of the 10 largest cities in their state and use this functional relationship to calculate the number of barrels and gallons of oil used by each city.
Starting from a brief look at functions and the mapping of domains to ranges, Sal starts out with an intuitive sense of what a function inverse is. He then, using an example, shows how to find the inverse of a function and also shows how the graph of the function and its inverse are reflections over the y = x line. This video provides a good review of function inverses for more advanced students or a nice introduction for the beginning student.
Are odd numbers connected to odd functions and even numbers to even functions? This video tries to clarify that connection. It also talks about functions that are neither odd nor even to give a more intuitive feeling about classifying these functions.
What does it mean for two things to have a functional relationship? In this video, Sal takes the example of a table of values that map a personÕs name to their height and discusses how this is a functional relationship. He also considers how the table could be changed so that the relationship is no longer a function.

We look at a number of different examples of functions and see what their domain is. Sal writes the domain in set notion and shows how different functions can have different input values that cause the function to be undefined.
After defining a simple function from a word problem, this video, shows how one could find the domain and the range of that function. The goals here are to reinforce the definitions of domain and range with a concrete example.
Collaborative learners will see the geometric addition of functions by graphing the sum of two graphed curves on the same coordinate plane. This task then naturally flows into giving learners the algebraic representation of the curves and having them build a table of values at various inputs with outputs of the two functions and their sum.
Students solve formulas by using substitution. In this algebra lesson, students utilize formulas introduced in the lesson which apply to science as well as volume and area. The lesson gives detailed instruction for solving each type of problem. Detailed answers to all practice problems are provided with step by step solutions to assist.
Students solve algebraic proportions. In this algebra lesson, students convert between fractions, percents and decimals. They solve problems using the distributive property.
