Question 14 (matching) A chopstick model of a catapult launches a marshmallow in a classroom The path of the marshmallow can be modeled by the quadratic h-0.05d2 d +2 for the domain 0d 30 14 13 12 D(21.83.0) 4 2 0 2 4 6 8 10 12 14 16 18 20 24 26 28 A(-1.83, 0) d- distance (feet) 2016 FlipSwitch. Created using GeoGebra. What does each point on the model represent in context? The point represents a zero of the model; however, it is below the domain, so it means nothing in context. point C The point represents a zero of the model, this means that the marshmallow travels close to 22 feet before it lands point B The point represents the vertex of the model: it means the marshmallow travels 10 feet before it reaches its max height of 7 feet. point D The point represents the lower value of the domain. It means that the marshmallow is at a height of 2 feet before it is released point A

Explanation / Answer

Point A represents a zero of the model, however it is below the domain. So it means nothing in context.

Point B represents the lower value of the domain. It means that the marshmallow is at a height of 2 feet before it is released.

Point C represents the vertex of the model, it means that the marsmallow travels 10 feet before it reaches its max height of 7 feet.

Point D represents a zero of the model, this means that the marshmallow travels close to 22 feet before it lands.
