Learn how to sketch the graph of a derived function
A derived function graph helps visualise the derivative of a function
The key to sketching a derived function graph is using the stationary points
No other key points on the original graph are needed to sketch the derived graph
Where the function is increasing the derived graph is above the x-axis
Where the function is decreasing the derived graph is below the x-axis
Where the function has stationary points the derived graph has roots
The derived graph should be of a type one power less then the function
