The function f(x) = −x2 + 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 xintercepts. What do these values mean in the context of the problem? (5 points)
PLEASE HELP ME!!!! :)

Best ResponseYou've already chosen the best response.2I am tied up right now. Perhaps someone else could help you with completing the square!

Best ResponseYou've already chosen the best response.2Completing the square: f(x) = −x2 + 48x − 432 =(x24)^2+576432 =(x24)^2+144 then x24=0, or x=24 is the location of the vertex, and f(x)=144.

Best ResponseYou've already chosen the best response.2To find the xintercepts, put f(x)=0, or (x24)^2+144=0 (x24)^2=144 Take square roots, x24=+144 or x24=144 Solve for x in each of the above cases to find the xintercept.
