A value of the input where a function changes from increasing to decreasing (as we go from left to right, that is, as the input variable increases) is called a local maximum. If a …Procedure to find where the function is increasing or decreasing : Find the first derivative. Then set f'(x) = 0; Put solutions on the number line. Separate the intervals. Choose random value from the interval and check them in the first derivative. If f(x) > 0, then the function is increasing in that particular interval. I want to find the increasing and decreasing intervals of a quadratic equation algebraically without calculus. The truth is I'm teaching a middle school student and I don't want to use the drawing of the graph to solve this question.So the interval f is increasing is (-π/2, 0) and (π/2, π). A function is decreasing when the first derivative is negative. That would occur when either both sine and cosine are positive or where both are negative. That would be in Q1 and Q3. So the interval f is decreasing is (-π, -π/2) and (0, π/2). Upvote • 0 Downvote. Add comment.First, take the derivative: Set equal to 0 and solve: Now test values on all sides of these to find when the function is positive, and therefore increasing. I will test the values of -6, 0, and 2. Since the values that are positive is when x=-6 and 2, the interval is increasing on the intervals that include these values. A value of the input where a function changes from increasing to decreasing (as we go from left to right, that is, as the input variable increases) is called a local maximum.
