Find the zeros of the function. You may want to view the graph of the function to help you identify the real root, then use it to depress the polynomial & find the remaining roots. f(x) = x3 + 5x2 – 3x - 15 O{-5, -73, 3} O{-5, -3, 3} O {5, -3, 3} - O{-V5, -V3, V3

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
