Consider the function [math]
Then [math] =
The following questions ask for endpoints of intervals of increase or decrease for the function [math].
Write INF for [math], MINF for [math], and NA (ie. not applicable) if there are no intervals of that type.

The interval of increase for [math] is from
to
The interval of decrease for [math] is from
to
[math] has a local minimum at . (Put NA if none.)
[math] has a local maximum at . (Put NA if none.)
Then [math] =
The following questions ask for endpoints of intervals of upward and downward concavity for the function [math].
Write INF for [math], MINF for [math], and put NA if there are no intervals of that type.

The interval of upward concavity for [math] is from
to
The interval of downward concavity for [math] is from
to
[math] has an inflection value, x = . (Put NA if none.)
