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

What is the value of x in the equation 2(x-4) = 4(2x + 1)?

The table below represents the displacement of a fish from its reef as a function of time: time (hours) x displacement from reef (feet) y 0 4 1 64 2 124 3 184 4 244 part a: what is the y-intercept of the function, and what does this tell you about the fish? (4 points) part b: calculate the average rate of change of the function represented by the table between x = 1 to x = 3 hours, and tell what the average rate represents. (4 points) part c: what would be the domain of the function if the fish continued to swim at this rate until it traveled 724 feet from the reef? (2 points)
