Someone Please Help!! 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?

The function represents an upside down u parabola. Hence the negative. On a parabola, we know the vertex is located here: |dw:1439328499546:dw|

We know that the vertex is at maximum and not minimum

the amount of profit gain is located in the y-axis. The vertex in max is located on the highest y-axis. Nothing goes further than that.

X-intercept is where the graph touches the x-axis. So what is y when a point is on the x-axis?

agree with the above but I think A is incomplete unless I missed that you also calculate the values
