Consider the function [math]. This function has two critical numbers [math]

Then [math] and [math] .

For each of the following intervals, tell whether [math] is increasing or decreasing.
[math]:
[math]:
[math]

The critical number [math] is and the critical number [math] is
There are two numbers [math] where either [math] or [math] is undefined.

Then [math] and [math] .

Finally for each of the following intervals, tell whether [math] is concave up or concave down.
[math]:
[math]
