in order to find intervals of function, we determine the intervals where the function has a positive first derivative . To find intervals, first we find the critical values, or points at which the first derivative of the function is equal to zero. For the given function the intervals would be
put zero in equation
put 1
put 2
put 3
hence we can see that the interval is from zero to positive infinity
