Vertex Form Proof
Hello mathematicians, puzzlers, and other curious people! Following up on this previous video, I\’m using calculus to come up with a proof of the vertex form of a quadratic function. Calc You Later! Side note: If any of those calculus steps, like the chain rule, were hard for you to follow, you can learn Calc…
Quadratic Graphing and Stretching
Hello mathematicians, puzzlers, and other curious people! This video is inspired by a question I received on Wyzant about applying some constant factor to one function, making a related function go through a particular point. If you\’d like to learn more about scaling quadratic and other functions, a related technique, more complicated because the numbers…
