Learn how function transformations affect the graphs of quadratic functions.

Solving_quadratic_equations_by_taking_square_root

In this tutorial you will learn about the most basic way of solving quadratic equations.

Graphing_quadratic_functions

In this tutorial, we will learn how to graph quadratic functions given in different forms.

Interpreting_quadratic_models

Use all the knowledge you gained about quadratic equations and functions in order to solve some word problems about real world contexts that are modeled by quadratic functions.

Features_of_quadratic_functions

Learn about the features of quadratic functions, and how to find them given the formula of the function. Also learn about the different forms of quadratic functions: standard, vertex, and factored.
