**Increasing and decreasing intervals OpenStax CNX**

I want to find the increasing and decreasing intervals of a quadratic equation algebraically without calculus. The truth is I'm teaching a middle school student and I don't want to use the drawing of the graph to solve this question.... To find increasing/decreasing intervals, just know that every interval with a minimum as the left bound and a maximum as the right bound is increasing, and vice versa.

**How do you find the interval of increase and decrease in a**

What are the increasing and decreasing intervals in a parabola? Update and increasing on the interval [math](a, \infty)[/math]. In the latter case, the parabola is increasing on [math](-\infty, a)[/math] and decreasing on the interval [math](a, \infty)[/math]. 19 .4k Views · View 4 Upvoters. Thank you for your feedback!

## How To Tell If An Interval Is Increasing Or Decreasing

### When stating where the quadratic function is increasing or decreasing we use the interval of the input to do this. For example, the graph below is a parabola opening upward with a vertex at

- Intro. Functions can either be increasing or decreasing for different intervals. And without looking at a graph of the function, you can't tell visually what a function is doing.
