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

    In context of the problem, what do you think the vertex represents based on the observation of this graph?

    Im not sure. Maybe the largest about of games sold?

    It is the largest profit

    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.

    Yes, but what are the profits in the number of games sold?

    Take a look at the graph.

    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
