If f(x)=\/x and g(x)=4\/x ,what transformation took place? f(x ) was vertically shrunk by a factor of 4 F(x) was reflected over the x-axis
f(x) was horizontally stretched by a factor of 4
F(x) was vertically stretched by a factor of 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

where's the diagram?
