Complete step-by-step investigation of quadratic functions, allowing the user to input the function. Each step, from solving f(x) = 0 to graphing and finding extreme points, is covered in depth, via links for each step (requires...

Gain an understanding of how to graph quadratic equations by viewing an example and a video lesson.

Lesson 1 of 4 for Passport to Advanced Math. Students will add, subtract, and multiply polynomials. They will build quadratic functions and write equations to represent a context.

A "glossary" definition of quadratic functions, including examples of quadratic and non-quadratic functions, and links to related definitions as well and graphs.

Analyze quadratic equations in order to determine how many different real number solutions they have. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

For this task, students work through the steps and operations involved in the composition of an explicit quadratic function. The task assumes that the students are familiar with the process of completing the square. Aligns with F-BF.B.3...

In this task, students are shown a table with linear, quadratic, and exponential functions at various values of x and are asked to match the function type to each data set and explain their reasoning. Aligns with F-LE.A.1.b and F-LE.A.1.c.

During this task, learners will realize that equivalent expressions produce the same graph. The lesson will lead to discussions about the value of different forms of equations. Aligns with F-IF.C.7.a, A-SSE.B.3, and F-IF.C.7.

Detailed math tutorial features notes and examples that investigate the process for graphing parabolas.
