Functions:graph B,mapping A, Table B
Grape B is a function because it passes the vertical line test ( meaning when I draw a vertical line any where on the graph the line only touched one point),mapping A is a function because each x value has only one y value same with table.
Non function: graph A, mapping B, Table A
Graph A does not pass vertical line test so it is not a function, mapping B and Table A both have an x value that has two y values and that is not a function.

Answer:
Y= -12
Step-by-step explanation:
6(y + 7) = 2(y - 3)
6y+42=2y-6
4y+42=-6
4y=-48
y=-12
<u>Answer:</u>
7th Place
<u>Step-by-step explanation:</u>
Seeing as how the number of runners in front of Paula is 
the number of runners behind her,
Assign the number of people behind Paula to a variable:
# of people behind Paula = b, which means
# of people ahead of Paula = b
Use the variable to make an equation:
b (people behind Paula) + b (people ahead of Paula) + 1 (Paula) = 25
b + b + 1 = 25
Solve for b:
b + b + 1 = 25
b + b = 24
b = 24
b = 18
If there are 18 people behind Paula, there are * 18 people in front of her, which is 6; This puts Paula in 7th place.
