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

$f'(x)$ =

Domain of $f(x)$ =

Domain of $f'(x)$ =
