Determine the largest open intervals of the domain over which the function is $($a$)$ increasing, $($b$)$ decreasing, and $($c$)$ constant. Then give the $($d$)$ domain and $($e$)$ range.

$($a$)$ Over what open interval$($s$),$ if any, is the function increasing? Select the correct choice below and, if necessary, fill in the answer box to complete your choice.

A$.$ The function is increasing on the open interval$($s$)$

$($Type your answer in interval notation. Use a comma to separate answers as needed.$)$

B$.$ The function is never increasing.
