Understanding Decreasing and Increasing Functions

In this post, we are going to discuss the meaning of increasing and decreasing functions.  Consider the graph of the function f shown below. If we trace the graph with the mouse pointer, we would be able to observe that the trace is moving upward from a to b, moving downward from b to c, and moving upward again from c to d.

Increasing and Decreasing Functions

In mathematics, we say that the function is increasing from a to b, decreasing from b to c, and increasing again from c to d. Now, let us elaborate what do we mean by increasing functions. » Read more
