WebFINDING INCREASING OR DECREASING INTERVALS 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. WebIf you start at 0 and go towards negative infinity, then yes, all the values are increasing. However, we are talking about increasing in terms of slope, so we move from left to right. If you started at negative infinity and moved towards 0, then all the values would be decreasing and there slope of the tangent line will be negative.

WebStep 4 - Write the increasing and decreasing intervals. In step 3, we have tested the points from each interval and substituted them in the derivative of a function. We had two intervals. In one interval the derivative of the function was less than 0, and in the other interval the derivative of the function was greater than zero.
