Answer:
$2282
Step-by-step explanation:
ƒ(x) = x(4564-x) = 4564x - x²
In standard form,
ƒ(x) = -x² + 4564x
a = -1; b = 4564; c = 0
This is the equation of an inverted parabola, because a < 0. Therefore, the vertex is a maximum.
The vertex of a parabola occurs at
x = -b/(2a) = -4564/[-2 × (-1)] = -4564/(-2) = 2282.
The price that will maximize the company's revenue is $2282.
The graph below shows that the company's maximum revenue is over $5.2 million.
