What is the rule for the reflection?
fy=x(x, y) - (y, -x)
fy=-x(x, y) - (-y, -x)
fy=x(x, y) - \, *)
Ô ty x(x, y) = (y, x)

english, cause i can’t you

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
