So, to say formally. That's the Intermediate Value Theorem. Once it reaches a value of 1.2, the function will increase. To determine the increasing and decreasing intervals, we use the first-order derivative test to check the sign of the derivative in each interval. That means that in the given region, this function must be either monotonically increasing or monotonically decreasing. A derivative is a point on the function that gives us the measure of the rate of change of the function at that particular point. Choose random value from the interval and check them in the first derivative. If the functions \(f\) and \(g\) are decreasing functions on an open interval \(I\), then the sum of the functions \(f+g\) is also decreasing on this interval.
