More generally, suppose f is continuous on [a, b] and differentiable on (a, b). Let g(x) = f(x) − f(b) − f(a) b − a (x − a) − f(a).If the point is either less than zero, or between zero and 5/2, the derivative evaluates to a negative number, which means the slope of the function evaluated at those points is negative, so the slope is negative, hence the function is decreasing in those intervals, which is what we were asked to find. Keep Studying!If the slope (or derivative) is positive, the function is increasing at that point. If it’s negative, the function is decreasing.

If for all , the function is said to be strictly decreasing. If the derivative of a continuous function satisfies on an open interval, then is increasing on . However, a function may increase on an interval without having a derivative defined at all points. And so using interval notation, we say that our function is increasing on the open interval from negative ∞ to negative 10 over 27 and the open interval from zero to ∞. And it’s decreasing for 𝑥-values on the open interval from negative 10 over 27 to zero. And of course it’s important that we realize that these must be open intervals.The space between contour lines on a topographical map is a contour interval.
