Quadratic Formula Domain The set of possible inputs for a function. Range The set of possible outputs of a function. Discriminant b² - 4ac > 0 then two distinct real roots. b² - 4ac = 0 then one repeated real root. b² - 4ac < 0 then a quadratic function has no real roots. Types of Lines for Regions If y < f(x) or y > f(x) then the curve y = f(x) is not included in the region, and is represented by a dotted line. If y ≤ f(x) or y ≥ f(x) ...
