Khan Academy: Inflection Points From Graphs of Function & Derivatives

Put everything together in a picture. Scholars take what they learned in the previous three lessons in the 15th segment of a 23-part unit to graph rational functions. They find the end behavior, the horizontal and vertical asymptotes if...

Double win with a comprehensive worksheet and an excellent worked out answer key. The worksheet itself is twelve pages and begins with the simple sine and cosine graphs, then, develops into the reciprocal trig functions. 

The slider feature on Desmos excellently shows how graphs change based on different variable values. Learners look at two similar rational functions and compare and discuss what happens when the numbers go from positive to zero to...

Extending his asymptotes lesson from the previous video, Sal shows viewers another example of graphing rational functions. This video is shorter than the previous one and could be shown in a single class session.

The inflection point, the point where the second derivative is zero, is the focus of a video  that works through a problem where it is not obvious to see the roots of a function. The solution to the problem requires using...

Time to take a second look at derivatives finding concavity. While watching the video, learners find out the definition of concavity. Individuals see how to determine whether an interval is concave up or concave down using graphs and the...

Finding the inflection points of a curve.

Demonstrates solutions to three problems. Problems address understanding of graphs of quadratic equations and translations of graphs of quadratic equations. [11:31]

Using the first and second derivatives to identify critical points and inflection points to graph the function.

Video about translating between the graph and equation of trigonometric functions. Examples consist of writing the equation a sine function from its graph and graphing a cosine function from its equation. [5:13]
