Use the critical points to break the domain up into intervals, and pull a test point from each interval. Plug each test point into the derivative of the function and evaluate. If the test point gives a positive output, then the function is increasing on the interva...

f(x) = x^3 - 9x^2 - 21x + 9 (a) Find the interval on which f is increasing. (b) Find the interval on which f is decreasing. Determine the interval in which the following function is decreasing: f(x) = x^4 - x^2 + 1. ...
An interval is said to be increasing if a point on the interval, say x=a, when the first derivative is a positive number f′(a)>0. On the other hand, the interval is decreasing if a value in the interval, say x=b, when the first derivative results to a negative va...
Consider the function f(x) = x3 - x2 + 9. Find the interval on which f is decreasing. Consider the following function: y = x^{2/3} + 3. Determine where the graph of the function is increasing and decreasing. Let f(x) = -2(x-4)^{2/3} + 5. On what intervals is the fun...
A local maxima or minima is a point on the graph where the function reaches the highest or lowest value in a specific interval. A global maxima or minima is the highest or lowest value of the function over the entire domain. Can a maxima and minima problem have multiple solutions?
On the other hand, in the interval $$(0, +\infty)$$, in the previous graph, we see that as the value of $$x$$ increases that of $$f(x)$$ decreases. In this case we say that the function is decreasing. A function $$f$$ is strictly decreasing in an interval of its domain ...
As a consequence, if we temporarily hold fixed, and also localize to a relatively short interval, then can only be non-decreasing in if is also non-decreasing at the same time. This turns out to significantly cut down on the possible length of a non-decreasing sequence in this regime, pa...
If a graph exists on an interval, it is doing one of three things Increasing (y-values increase as x increases) Decreasing (y-values decrease as x increases) Staying constant (y values stay the same as x increases) The derivatives tell us this information because it tells us the slope. ...
Consider the function of the graph given above. The function is decreasing on the interval(s) given by ___. Consider the function f(x) = x^4 - 4x^3. Determine intervals where the function is increasing and where it is decreasing. Consider ...
