Since this is a quadratic function with a negative leading coefficient, the graph of the function will be a parabola opening downwards, and the maximum value will occur at the vertex. The vertex of a parabola in the form of \(f(x) = ax^2 + bx + c\) can be found Show more…

A potter is selling vases. The function p gives the total profit p(x), in dollars, the potter will receive if the vases are sold at a price of x dollars each. The graph of y = p(x) is shown. What equation represents the relationship between the price of one vase and the profit? A) p(x) = -6(x - 18)^2 + 34 B) p(x) = -6(x - 18)^2 + 1536 C) p(x) = -6(x - 34)^2 + 18 D) p(x) = -6(x - 34)^2 + 1536
