Answer:
$16,000
Step-by-step explanation:
Revenue is the product of price and the number sold. Using the given relation for number sold, the revenue as a function of price is ...
R(p) = p(-40p +1600) = -40p(p -40)
This is the equation of a quadratic that opens downward and has zeros at p=0 and p=40. The vertex is halfway between those zeros, at p=20. The revenue at this price is ...
R(20) = -40·20(20 -40) = 16,000 . . . . dollars

Answer:
Option C
Step-by-step explanation:
If the graph of a function shows the end behavior as,
1). As x approaches negative infinity, y approaches negative infinity.
2). As x approaches positive infinity, y approaches negative infinity.
That means both the ends of the graph are downwards and the function is a quadratic function.
From the given options,
y = -3x² + 4 is a quadratic function.
Therefore, Option C will be the correct option.
