What is the difference quotient?
In this post, we will be interpreting and using the difference quotient \frac{f(x+h)-f(x)}{h} as the average rate of change of f(x) or the gradient of a chord or secant of the graph y = f(x) , as a part of the Prelim Maths Advanced course under the topic Calculus and sub-part Difference Quotients.
