What is the equation of a parabola that passes through the points (–1, 4), (0, 5), and (2, –11)? These are the options:
A. y = –3x^2 + 2x + 5
B. y = –2x^2 – 3x + 5
C. y = –3x^2 – 2x + 5
D. y = –2x^2 + 3x + 5

So don't take my word i'm not exactly a mathematical person but i would assume a. because while selling the soap every month you increase in sells so you would by 11 percent. the you would get the factor 0.89 which if i had to guess would be the monthly profit over 11 probably wrong tho
