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.If the slope (or derivative) is positive, the function is increasing at that point. If it’s negative, the function is decreasing. So to find intervals of a function that are either decreasing or increasing, take the derivative and plug in a few values.
