Introduction
The purpose of this lecture is to develop mathematical tools
that can be used to determine the exact shape of a graph
and the precise locations of its key features such as local
extremes, inflections, intervals of increasing/decreasing,
upward/downward concavities.

## 4. Increasing and decreasing functions

Foundation Year Program
Increasing and decreasing functions
The terms increasing, decreasing, and constant are used to describe
the behavior of a function as we travel left to right along its graph.
The function in the figure can be described as
increasing to the left of
