Fan and medal!!!!! The function f(x) = −x^2 + 48x − 432 models the profit, in dollars, a game developer makes for selling a new game, where x is the number of games 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)

    have you written this correctly? it implies that the profit falls rapidly as he sells more units Are you sure there is a - sign before x^2 ?

    well - you should recognise a quadratic equation I hope the vertex is the max OR min values and you should know what the x intercepts are : the points where y = 0 this question doesn't make sense to me - but treat it as any other quadratic
