In this activity, students explore the standard form of a quadratic equation, y = ax 2 + bx + c. They explore how the x-intercepts (zeros), y-intercept, and vertex are related to the graph of the standard form of a quadratic function.

Launching a rocket up into the air, throwing a textbook down off a rooftop, or tossing a baseball out to someone in center field are all examples of projectile motion and quadratic word problems. Situations like these are explored here,...

This activity has students find patterns in the areas and perimeters of a given series of figures. Students' then use graphing calculators to graph the values and to find linear and quadratic functions to describe the patterns.

The Quadratic Transformer was developed to support the learning of quadratic functions, and in particular to help you understand the connections between symbolic and graphic representations. Indirectly, it also helps you connect either...

Students solve quadratic inequalities using graphs, tables, and algebraic methods.

Students will explore the effect the coefficient of x^2 has on the graph of a quadratic function; they will also explore the effect of adding a constant to the quadratic function.

In this activity, you will change the parameters of the function and determine the effects on its graph and its vertex.

The mathematics tutorial explores quadratic inequalities. The lesson consists of class notes, calculator tips, examples, and practice problems with solutions. The teacher resource includes a worksheet on matching graphs with equations.

In this activity, students will plot the graphs of systems of equations and determine the number of real solutions of the system. Then find the solution of the system algebraically.

In this task, students find a unique linear function, a unique exponential function, and more than one quadratic function that go through the same two points on the coordinate grid. Aligns with F-LE.A.

This resource provides an overview of graphing, giving examples of general polynomial, radical, rational, and piecewise functions. Also includes advice on common mistakes made by students.

A lesson, practice exercise, and resource for use when planning classroom instruction on linear quadratic systems. Find definitions, example equations and graphs, a four-question quiz with solutions, and an activity through which...

Analyze the numerical and graphical representations of functions. This interactive exercise focuses comparing linear, quadratic, and exponential functions and their graphical representations after completing a table to calculate ordered...

Here is a site that clearly and thoroughly explains the graphs of the major mathematical functions. There are example problems solved, problems for the student to attempt, and answers to the student problems. Point this site out to...

Learn how to graph parabolas with this quick tutorial.

This site compares the graphs of three quadratic functions, and explains how certain characteristics of the graph relate to properties of the equations and their solutions. Contains practice problems, including real-world examples.

Graph quadratic functions that are given in the vertex form. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

Based off of the hit television show NUMB3RS, this lesson helps students understand how changing the values of y=a(x-b)^2+c changes the graph of the associated parabola. This is framed in the context of a bridge jumper, who enters the...
