  • 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…
