Writing Equations of Parabolas in Vertex Form

Augment a unit on parabolas with an instructive math activity. Pupils graph parabolas by examining the relationship between the focus and directrix. 

Here is a study guide that breaks graphing quadratic functions into three simple steps. Quadratic functions in vertex and intercept form are included. Use during a lesson or afterward for skills practice. Note: Make sure your class has...

Explore graphing quadratic functions by writing them in vertex form. Learners use their skills of completing the square to rewrite standard form in vertex form. They recognize key features in the equation and transfer them to the graph,...

This is the last of three well-done videos on identifying and graphing conic sections from an equation. Here, Sal graphs a circle that is not centered at the origin and a parabola that opens downward.

This is the last of three well-done videos on identifying and graphing conic sections from an equation. Here, Sal shows how to graph a circle not centered at the origin and a parabola that opens downward.

Students review how to graph parabolas. They practice graphing two different parabolas using the vertex and table method. They solve problems related to graphing circles, determining the radius and the center.

What does a square have to do with a quadratic function? Young scholars learn that completing an algebraic square is helpful when graphing the quadratic functions. The video instructor demonstrates rewriting quadratic functions in vertex...

Watch this video and find out how to graph a quadratic equation when it's in intercept form! After going through the different forms of quadratic equations, an instructor leads viewers through an example problem. For the example problem,...

Show your class how to use properties to make graphing easier with a resource that explores the graphs of quadratics. Using tables to determine the points to graph, pupils discover the symmetry of parabolas in...

The vertex of an upward facing parabola is the lowest point on the parabola and is called the minimum. The vertex on a downward facing parabola is the highest point on the parabola and is called the maximum. These are the two...
