Question

Please help I'll give a medal!

The function f(x)=-x^2 + 44x -384 models the daily profit, in dollars, a shop makes for selling donut combos, where x is the number of combos 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?

Part B: Determine the x-intercepts. What do these values mean in the context of the problem?

Answer 1

And I'll fan

Answer 2

Anyone??

Answer 3

do you know how to factor a quadratic? or use the quadratic formula to find the x values?

Answer 4

Kind of, not really

Answer 5

the vertex is the maximum or minimum point for the quadratic function

Answer 6

So how do I solve it?

Answer 7

If your looking to find the coordinates of the vertex you can use the equation\[x=\frac{ -b }{ 2a }\]This will give you a x coordinate which you can plug back into the original function to find the y-coordinate.

Answer 8

For part A?
