What is the range of the given function?
{(-2, 0), (-4, -3), (2, -9), (0,5), (-5, 7)}
{x | x = -5, 4,-2, 0, 2}
{yl y = -9, -3, 0, 5, 7}
{x | x = -9,-5, 4, -3, -2, 0, 2, 5, 7}
{yly = -9, -5, 4, -3, -2, 0, 2, 5, 7}

5/12, or 5: 12

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

answer: its the third option.
