NOTE: When using interval notation in WeBWorK, remember that:
        You use 'INF' for [math] and '-INF' for [math].
        And use 'U' for the union symbol.
Enter DNE if an answer does not exist.


a) Give the domain of [math] (in interval notation)

b) Find the critical numbers of [math]. (Separate multiple answers by commas.)

c) Determine the intervals on which [math] is increasing and decreasing.
[math] is increasing on:
[math] is decreasing on:

d) Use the First Derivative Test to determine whether each critical point is a relative maximum, minimum, or neither.
Relative maxima occur at [math] (Separate multiple answers by commas.)
Relative minima occur at [math] (Separate multiple answers by commas.)
