Domain: (-3, 7)

General Formulas and Concepts:

Algebra I

Step-by-step explanation:

According to the graph, our x-values span from -3 to 7. Since both are open dot, they are exclusive from the domain:

Interval Notation (-3, 7)

Inequality Notation -3 < x < 7

linear pair postulates

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
