The function f(x) = –x2 + 28x – 192 models the hourly profit, in dollars, a shop makes for selling sodas, where x is the number of sodas 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)

Answer 1

The vertex is at 14, 4. The vertex is the is the point of the parabola where the line reverse basically.


The x-intercepts are (12,0) and (16,0) and are where the parabola goes through the x-axis.

I hope that this helps.

Thanks for the brainly.

Answer 2

Part A: The vertex is (14, 4). When they sell 14 sodas, they make $4 profit.
Part B: The x-intercepts are when f(x) is 0, so they are (12, 0) and (16, 0). When they sell 12 and 16 sodas, they don't make any profit.
