You can often be asked to state the range of values of x for which a given graph is increasing or decreasing. In the next video tutorial I take you through an example explaining increasing and decreasing functions and how to find the range of values for which it is increasing and decreasing
Stationary Points (Maximum, Minimum and Inflexion)
In the first of these videos I explain what we mean by stationary points and the different types of stationary points you can have.
In this example I demonstrate how to find stationary points. Answer only... or watch the video
You will need to be able to distinguish if a point is a maximum, minimum or point of inflexion without drawing the graph. In the next video link I show you two methods.
In this next example I put together all the ideas discussed above. Answer only
The following questions will hopefully give you an idea of what you can expect to be asked on differentiation. They are taken from the Edexcel board but can equally apply to other boards.
