The profit of a company XYZ can be modeled by a quadratic equation. During XYZ’s 3rd year it recorded its maximum daily profit $100. This maximum be denoted by the ordered pair (3, 100). Also during its 4th year of business, it recorded a daily profit of $80. This can be denoted by the ordered pair (4, 80). What is the vertex form of the quadratic equation that fits the model for the profit of XYZ company?

Select one:
a. y = -4(x + 3)2 + 80
b. y = -20(x - 3)2 + 100
c. y = 20 (x + 3)2 + 100
d. y = 4(x - 3)2 + 100
