The function f(x) = –x2 + 24x – 80 models the hourly profit, in dollars, a shop makes for selling coffee, where x is the number of cups of coffee 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) I have the vertex and the x-intercepts but i need to know what they mean in the context of the problem.

The vertex is the maximum y-value of the function. In terms of context, it is when the most amount of profit is obtained during the hour. 

The x-intercepts are when the number when the amount of profit selling coffee is equal to 0. 

Hope this helps!!
