state the domain of the relation.

a) {-4, -3, -2, -1, 0, 2, 5, 8}

b) {-4, -3, -2, -1, 0}

c) {-4, -3, -2, -1}

d) {-4, -1, 2, 5, 8}

$4

step-by-step explanation:

$30×5=$150

$150 minus $130=$20

$20÷5=$4.

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
