Finding the Vertex of a Quadratic Function

Keep your mathematicians engaged using this group linear functions activity. Each of ten groups receives two graphs with both an image and equation, as well as a "who has" phrase to call out the next graph. Scholars stay on their toes as...

Seeing functions in nature is a beautiful part of mathematics by analyzing the motion of a dolphin over time. Then take a look at the value of a stock and maximize the profit of a new toy. Explore the application of quadratics by...

What is absolute value? What is an absolute value function? Emerging mathematicians solve equations containing variables inside an absolute value sign.  They graph each function on a coordinate plane and identify the maximum and...

Match the graph with its function in an exercise that focuses on variations of the graph of y = e^x. Learners are given four graphs on the same set of axes and four functions, all involving e^x. The task is to match each...

After correcting the last problem in his previous video, Sal explains how to graph quadratic functions. Those with difficulty graphing algebraic functions will find Sal's instruction and easygoing manner a welcome change from staring at...

The central concept in this video is solving quadratics by factoring. Several examples are shown with positive and negative numbers. The instructor demonstrates setting the factored equation to zero to solve the quadratic, using a graph...

With his trusty graphing calculator, Sal begins his lecture on solving quadratic functions by graphing. The video is a good way to show young mathematicians not only how to use the graphing calculator (which Sal describes as "archaic"...

High schoolers analyze the vertex form of a parabola and find an approximate fit of a model. They explain the quadratic parabola function and its properties by developing quadratic models. They use translation and dilation to change the...

Given a graph or verbal description of a function, the student will determine whether the parent function is quadratic or linear.

Get ready to set the standard! Pupils watch a video on how to graph a parabola from a quadratic in standard form without converting the form. Scholars learn how to find the axis of symmetry from the equation and from there the vertex....
