The function f(x) = −x2 + 44x − 384 models the daily profit, in dollars, a shop makes for selling donut combos, where x is the number of combos sold and f(x) is the amount of profit. Part A: Determine the vertex. What does this calculation mean in the context of the problem? (5 points) Part B: Determine the x-intercepts. What do these values mean in the context of the problem? (5 points)

    the x-intercepts are where f(x) = 0 i.e. where the profit is zero. it is where they break even

    The vertex of a parabola that opens down, is the maximum point of the parabola. In this case, the maximum point is the maximum daily possible profit. the vertex in a form of (h,k): k - the maximum possible daily profit h - how many combos do you have to sell to reach this max. profit.

    the vertex can be found by completing the square.

    in other words the y-value of the vertex - the maximum possible daily profit the x-value of the vertex - how many combos do you have to sell to reach this max. profit.
