Quadratic Function Teacher Resources

This activity allows students to use real data obtained by them to model quadratic equations. students can use the TI-83 and/or TI-84 and a motion detector to collect their data. The students will then manually fit both quadratic and...

Explore the term cubic function and assess learning with a quiz.

Students recognize the effects of changes in parameters on the graphs of linear, quadratic, and exponential functions.

Solve real-world word problems that involve quadratic models. In this exercise, that models are given in standard form.

This site offers an introduction to quadratic equations. Includes hyperlinked terms and examples.

Video defining the vertex and axis of symmetry for a parabola. The vertex is found for a specific function by completing the square to change the equation from standard form to vertex form and then reasoning through the equation.

The domain of a function is all the possible values of x's of ordered pairs; whereas the range of a function is all the possible values of y's of ordered pairs. You can easily find them by graphing the functions or ordered pairs. Let's...

Video tutorial serves as an introduction to polynomial functions. Learn what they are, how to recognize them, and how to classify them. [13:09]

This is an interactive activity to explore the second-degree polynomial function. It goes from the simplest case, y=x^2 to different translations.

In this section different interactive activities are presented which can be used as supplementary material to traditional classroom and allow for interactive study of mathematics.

For this task, students are presented with a graph and asked to identify the functions that could be represented by it and explain their thinking. The task addresses knowledge related to interpreting forms of functions derived by...

Enter two complex numbers (z and c) as ordered pairs of real numbers, then click a button to iterate step by step. The iterates are graphed in the x-y plane and printed out in table form.

Students use their knowledge of the vertex form of a quadratic equation to graph parabolas, given a specific move to make.

1. Students will be able to review how to find the vertex of a parabola using a graphing calculator. 2. Students will be able to observe the relationship between the values of a, h and k and the graph of a parabola in vertex form. 3....

The upwards or downwards of a function on a graph is shown in this lesson. It is 4 of 7 in the series titled "Shifting Up and Down."

In this lesson, students translate between pictorial, written, and verbal representations of polynomials.

In this activity, students collect data for a bouncing ball using a motion detector. They analyze the data and attempt to find a model for the height of the ball as a function of time.

A teaching activity that makes the equivalence and zeros connection between functions.

This StudyCard set is a teaching activity that uses real-world contexts to assist students in understanding the concepts of maximum, minimum, increasing, and decreasing.

Students will explore the effect of "c" on y = x2.

In this activity, students' will use a motion detector to measure how the position of a cart on a ramp changes with time. They will then determine a parabolic model for the position data using the intercepts.

In this activity, students will find both the kinetic and potential energies as the cart rolls down the ramp. They will find the sum of the two energies, and show that this value is constant at all times.

Students are introduced to an interesting property of parabolas and a method of proving that property using the TI-89 scripts. They then use the CAS of their TI-89 to generalize upon specific results.

Students explore curve fitting and translations of the parabola.
