Which function in vertex form is equivalent to f(x) = x2 + 8 – 16x?
f(x) = (x – 3)2 - 56
Of(x) = (x – 4)2 + 0
Of(x) = (x + 8)2 - 72
O f(x) = (x + 4)2 – 32

step-by-step explanation:

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
