What is an increasing or decreasing interval of a parabola? is it like the vertex or turning point of the parabola? i don't remember. : (

Well first, an interval is a set of real numbers, usually x values. For example 0 ≤ x ≤ 1 is an interval. If the y values for the x values of the set increase as the x values increase, then the interval is increasing. If the y values for the x values of the set decrease as the x values increase, then the interval is decreasing. I hope that wasn't confusing, if you have questions, ask.

Well let’s see here we need nuts and more nuts and probably more nuts so why not‍♂️

U ok yeah u go do that
