Ответ:
The vertex form y-k = a(x-h)^2 where (h,k) is the vertex, and y is the y-intercept.
So, plug the values in.
11,000-24,000 = a(0-500)^2
-13,000=250,000a
a=-0.052
y-24,000 = -0.052(x-500)^2
y= -0.052(x-500)^2 + 24,000
This is the second equation in the system.
The answer is then A, which contain the system of equations which can be used to determine must be sold for the company to make a profit.
