Pls Help. No fake answers. I need this Done soon, and I am willing to give brainlist to someone who does all of them. 1-4 = find the Domains, Ranges and determine if they are functions

1. {(-3,3) , (1,1) , (0, -2), (1,-4) , (5,1)}

2. {x = -2, -1, 0, 1, 2} {y = -7, -2, 1, -2, -7}

3. (Graph in screenshot)

4.(Graph in screenshot)

5. Given the function y=3x+5, find the rang if the domain is {-4, -1, 2, 5}

6-7: Complete the function tables, then graph the equation (I only need function tables)

6: y=4x+1 {x = -1, 0, 1, 2}

7: y = -2/3 x + 2

If p(x) is the total value of the production when there are x workers in a plant, then the average productivity of the workforce at the plant is a(x) = p(x) x . (a) find a'(x). a'(x) = xp'(x) − p(x) x a'(x) = xp'(x) − p(x) x2 a'(x) = p'(x) − p(x) x a'(x) = xp'(x) − p'(x) x2 a'(x) = p'(x) − xp(x) x2 why does the company want to hire more workers if a'(x) > 0? a'(x) > 0 ⇒ a(x) is ; that is, the average productivity as the size of the workforce increases. (b) if p'(x) is greater than the average productivity, which of the following must be true? p'(x) − xp(x) > 0 p'(x) − xp(x) < 0 xp'(x) − p'(x) > 0 xp'(x) − p(x) < 0 xp'(x) − p(x) > 0
