minimums for the given function are true? choose three
options.
over the interval [1, 3], the local minimum is 0
over the interval [2, 4], the local minimum is-8.
over the interval [3, 5), the local minimum is -8.
over the interval [1,4], the local maximum is 0.
over the interval [3, 5), the local maximum is 0.

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

7 is the median   7.875 is the mean
