❖ Sketching the Derivative of a Function ❖

(   • Sketching the Derivative of a Function  ) Longer Updated Version Sketching the Derivative of a Function - In this video, I sketch the derivative of two different functions. That is, I give the graph of y = f(x), and do a rough sketch of the graph f ' (x). To begin, I often try to look for places where the derivative is undefined (cusps on f(x) ) or where the tangent line would have a slope of zero.
