Determine the intervals of increase
WebFind the interval(s) where the following function is increasing. Graph to double check your answer. Possible Answers: Never Always Correct answer: Explanation: To find when a function is increasing, you must first take the derivative, then set it equal to 0, and then find between which zero values the function is positive. WebIntervals of Increase and Decrease A function is increasing when the graph goes up as you travel along it from left to right. A function is decreasing when the graph goes down as you travel along it from left to right. A function is constant when the graph is a perfectly at horizontal line. For example:

Finding intervals of increase and decrease of a function can be done using either a graph of the function or its derivative. These intervals of increase and decrease are important in finding critical points, and are also a key part of defining relative maxima and minima and inflection points. Calculus Applications of the Derivative. easy homemade egyptian kebabs recipeWebTake the derivative of the function. Find the critical values (solve for f ' ( x) = 0) These give us our intervals. Now, choose a value that lies in each of these intervals, and plug them into the derivative. If the value is positive, then that interval is increasing. If the value is negative, then that interval is decreasing. easy homemade flaky pie crust with butterWebVideo Transcript.
