Procedure to find where the function is increasing or decreasing :

Find the intervals on which f is increasing or decreasing calculator. Function increasing or decreasing calculator ; Increasing and decreasing intervals calculator ; (b) find the local maximum and minimum values of f.

Put solutions on the number line. Even if you have to go a step further and “prove” where. For that, check the derivative of the function in this.

F ′ ( x) = 3 ( 3) 2 − 18 ( 3) + 24 = − 3 so, the value is decreasing. Graph the function (i used the graphing calculator at desmos.com ). This is an easy way to find function intervals.

That means that in the given region, this function must be either monotonically increasing or monotonically decreasing. F ′ ( x) = 3 ( 0) 2 − 18 ( 0) + 24 = 24 so, the value is increasing the interval ( [ 0, 2) ) since it is positive value.
