Graph the function (i used the graphing calculator at.

Find the intervals on which f is increasing calculator. But when (which amounts in solving an inequality). (a) find the intervals on which f is increasing or decreasing. Find the intervals on which f is increasing and the intervals on which it is decreasing.

In calculus, increasing and decreasing functions are the functions for which the value of f (x) increases and decreases, respectively, with the increase in the value of x. (b) find the local maximum and minimum values of f. Procedure to find where the function is increasing or decreasing :

Once such intervals are known, it is not very difficult to. ( − ∞, − 1) ∪ ( − 1, 3) ∪ (. I set the derivative equal to 0:

And then construct the intervals: F (x)=x3 + 2x select the correat choice below and,if necessary, il in the answer box. Suppone that f in a continuous on ta, b] and differentiable on the open interval ( a, b).

X = − 1, x = 3, x = 6. This information can be used to find out the intervals or the regions where the function is increasing or decreasing. If the function is never increasing or decreasing, enter na in the associated.

The first derivative test for increasing / decreasing of a function : Great, it is in standard form, we see the answer. (c) find the intervals of concavity and the inflection.
