Please Help :) Thanks!

Step-by-step explanation:

f(n)= 3n+2

hence

1) for n= -2  

f(-2) = 3(-2)+2 =-6+2= -4

2) for n= -1

f(-1) = 3(-1)+2 =-1

3) for n=0

f(0)=3(0)+2 = 2

4) for n=1

f(1) =3(1)+2 =5

5) for n=2

f(2)=3(2)+2 =8

Hence  "C" option is correct

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
