15PTS!!! Suppose the manufacturer of a clothes washer has found that, when the unit price is p dollars, the revenue R is R(p) = -4p^2 + 4000p. What unit price should be established for the washer to maximize the revenue? (Hint: The vertex of a parabola is the maximum or minimum.)

He graph of f(x) = |x| is stretched by a factor of 0.3 and translated down 4 units. which statement about the domain and range of each function is correct? the range of the transformed function and the parent function are both all real numbers greater than or equal to 4. the domain of the transformed function is all real numbers and is, therefore, different from that of the parent function. the range of the transformed function is all real numbers greater than or equal to 0 and is, therefore, different from that of the parent function. the domain of the transformed function and the parent function are both all real numbers.
