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.A function is said to be decreasing (not strictly, in the broad sense) if for all x1 <x2,f(x1)≥f(x2) x 1 < x 2, f ( x 1) ≥ f ( x 2) Example: The function f(x)= −x+1 f ( x) = − x + 1 is decreasing over its whole domain of definition R R, hense its monotony. The decrease of a function can also be defined over an interval.We can find the increasing and decreasing regions of a function from its graph, so one way of answering this question is to sketch the curve, ℎ ( 𝑥) = − 1 7 − 𝑥 − 5.
