Identity the zero of the function y= x (x-4)(x+2)

- 2, 0 or 4

Step-by-step explanation:

y = x(x - 4)(x + 2)

x' = 0

x - 4 = 0

x" = 4

x + 2 = 0

x"' = - 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
