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 x-intercepts. What do these values mean in the context of the problem? (5 points) PLEASE HELP ME!!!! :)

    |dw:1438708054783:dw| You can solve for the vertex and x-intercepts using completing the square.

    I am tied up right now. Perhaps someone else could help you with completing the square!

    Completing the square: f(x) = −x2 + 48x − 432 =-(x-24)^2+576-432 =-(x-24)^2+144 then x-24=0, or x=24 is the location of the vertex, and f(x)=144.

    To find the x-intercepts, put f(x)=0, or -(x-24)^2+144=0 (x-24)^2=144 Take square roots, x-24=+144 or x-24=-144 Solve for x in each of the above cases to find the x-intercept.
