There is 1 solution

Step-by-step explanation:

y = -3 (x+1) ^2

Using the zero product property

0 =  -3 (x+1) ^2

Divide by -3

0 =   (x+1) ^2

Take the square root of each side

sqrt(0) =  sqrt( (x+1) ^2)

0 = x+1

Subtract 1 from each side

-1 =x

step-by-step explanation:

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
