Properties of Quad Functions

Landon has the option to choose between two investment opportunities. One investment can be modeled with exponential growth. The other investment can be modeled with a quadratic function. The amount of money Landon would have with each investment after x years can be shown in the accompanying graph.

When will the quadratic investment be worth $0?

• When x = 320

• When x = 9

• It never reaches $0

• When x = 20

The graph of a quadratic function is called a

• Parabola

• Vertex

• Axis of Symmetry 

• Vertex Form
