Big Ideas: Quadratic and square root relations can arise in the context of real world applications, and the domain and range of these relations can be affected by the context of the situation. In this lesson, students will write a quadratic equation describing a real world situation and then use inverse operations to rewrite the equation as a square root equation. The domain and range of both equations will be examined in the context of the real-world situation. Vocabulary: square, square root, inverse, domain, range
