PLEASE HELP The graph of Ax), shown BY below, resembles the graph of G(x) = 7, but it has
been changed somewhat. Which of the following could be the equation of
F(x)?
O A. F(x) = 3(x - 4)2 - 4
O B. FX) = 3(x+4)2 + 4
C. Fx) = -3(x-4)2 + 4
D. F(x) = -3(x+4)2 + 4

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
