Quizplus · Accepted Answer

To determine the intervals of increasing and decreasing of the given function, we need to find its derivative first. 
The derivative of 11eaa88b_9206_5380_a696_3dc9b103cdde_TB5869_11 is simply a constant, hence it is always increasing. 
Therefore, the correct answer is B as it is the only choice that includes both increasing and decreasing intervals.
