Using the chain rule, g' (x) = 2 (5 - x) Step 2: Find the zeros of the derivative function. In other words, find the values of for which g (x) equals zero.A function is considered increasing on an interval whenever the derivative is positive over that interval. And the function is decreasing on any interval in which the derivative is negative. How do we determine the intervals? The first step is to take the derivative of the function. Then solve for any points where the derivative equals 0.This means the point $(3, 0)$ should be included in the interval of decrease. Similarly, if you look at just the right half of the parabola, any given point is lower than all the points that come after it, even for $(3, 0)$. This means the point $(3, 0)$ is also part of the interval of increase.Explore math with our beautiful, free online graphing calculator.
