Domain and Range �Objective: SWBAT �DOL: identify the domain of a quadratic function given a graph or real life application. �(2. 1. b. ii) CCSS: F-IF. 5 Given 2 multiple choice and 1 CR, sw identify the domain and range of a quadratic function with 100% accuracy
Vocabulary �Domain: All possible input values, x values. Parabola always getting wider therefore the domain is always (-∞, ∞) �Range: All possible output values, y values. Since we have minimum or maximum point the y-value always limited
Graphs: Notes �Find the domain and range from the following graph: Domain: (-∞, ∞ ) Range: (-∞, 4]
