The intervals between level 1 thorugh 9 are equal. Compare the differences in population from level 1 to 5 and from 6 to 9. Are they equal ? Why or why not ?

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

1 + (6 / x - 1)
