If Rx) = 5x - 3, which expression represents its inverse function?

A. (x + 3)
(x + 2)
B. (x + 3)
(b)
C. (5)
(x + 3)
D. (x - 3)
(2)

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

y/x of point b= y/x of point a
