The function f(x) = -x2 + 36x-224 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? (Vocabulary: increasing, decreasing, minimum, and maximum) (4 points)
Part B: Determine the x-intercepts. What do these values mean in the context of the
problem? (4 points)

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
