Answer:
Those functions are for a graph.
Step-by-step explanation:
You can compare them by heading to a website like desmos and plugging in each function, I think they even do tables as well. 
These are functions that can be graphed, I assume you know what that is, if not, look it up.

Answer:
4
Step-by-step explanation:
(10 - x ) / x = 3/2                Cross Multiply
2*(10 - x) = 3x                    Remove the brackets
20 - 2x = 3x                       Add 2x to both sides
20 = 3x + 2x
5x = 20                              Divide both sides by 5
x = 20/5
x = 4
