Maximum_and_minimum_points

Learn about maximum and minimum points of functions.

Recognizing_functions

Learn how to distinguish between two-variable relationships that are functions and two-variable relationships that aren't functions.

Interpreting_features_of_graphs

Interpret the graphs of functions in terms of the contexts that are modeled by the functions.

Intervals_where_a_function_is_positive_negative_increasing_or_decreasing

Learn about features of functions that have distinct graphical representations: intervals where the function is always positive or always negative, and intervals where the function is always increasing or always decreasing.

Interpreting_function_notation

Solve some word problems by interpreting expressions of modeling functions.

Inputs_and_outputs_of_a_function

Extend your understanding of the relationship between the inputs of a function and the outputs of that function.

Evaluating_functions

Learn how to find the value of a function for a given input value.

Introduction_to_the_domain_and_range_of_a_function

Learn what the domain and the range of a function are. Practice finding the domain and the range of a function given its graph.

Functions_and_equations

Understand the subtle differences and similarities between functions and equations. In this exercise, we will see how an equation can be turned into a function.

Average_rate_of_change

Learn what's the average rate of change of a function and how to find it over given intervals.

Average_rate_of_change_word_problems

Solve word problems that concern the average rate of change of a functional relationship.

Determining_the_domain_of_a_function

Determine the domains of functions according to various considerations.

Piecewise_functions

Piecewise functions are functions that have different assignment rules for different numbers. For example, a function can return x² for any negative x-value and return x³ for any non-negative x-value.
