PLEASE HELP The table has two functions, one given by an equation and the second represented by a graph. Let’s find the unit rates and y-intercepts of the two functions and compare them. What are the unit rates for function I and function II?
Which function has the greater unit rate?
What are the y-intercepts for function I and function II?

this looks really hard

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
