Given the graph of the function f. Find the interval(s) over which the function is increasing. Increasing Intervals of a Function: Increasing intervals are when the values of theyvariable increase along with the values of thexvariable. For example, we can verify t...
In our second example, we will use the derivative to find intervals of increase and decrease of a quadratic function. Example 2: Finding the Intervals of Increase and Decrease of a Quadratic Function Determine the intervals on which the function 𝑓(𝑥)=(−3𝑥−12) is increasing ...
Determine the domain of the function. Find the derivative of the function. Set the derivative equal to 0, and solve forxto find the critical points of the function. Use the critical points to break the domain up into intervals, and pull a test point from each ...

The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each
In summary, to find the intervals where the function is increasing and decreasing, you would need to find the first derivative and then solve the resulting 3rd order equation. This can be done by creating a sign chart of the first derivative and finding the critical points. One of th...
