Use the definition of the derivative (don't be tempted to take shortcuts!) to find the derivative of the function [math] Then state the domain of the function and the domain of the derivative.
Note: When entering interval notation in WeBWorK, use infinity for [math], -infinity for [math], and U for the union symbol. If the set is empty, enter " \lbrace \rbrace" without the quotation marks.
