This App is a quick reference guide to solving quadratic inequalities by sketching their associated graphs.
It’s ideal for students as the menu design reinforces each problem solving step. Examples highlight and simplify algebra that students find hard.
Large, crystal clear text and graphics make the app ideal for quick reference or a longer read.
You go step by step through example questions,
– Writing in general form
– Finding the graph shape
– Finding the x-intercept(s) if any
– Sketching the graph
– Finding the solution by inspection
or go straight to a particular step.
Examples cover major types of quadratic inequalities and feature finding x-intercepts by factoring, completing the square and the quadratic formula.
