Negative 1 less-than x less-than-or-equal-to negative 3 b. Negative 2 greater-than x greater-than-or-equal-to negative 4 d. Negative 1 greater-than x greater-than-or-equal-to negative 3

3; 9 is 8 to -4

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

ask the math teacher she or he would know lol.
