Answer 2

Answer:

Step-by-step explanation:  

Well a function has only one answer for y for every x. f(x) or g(x) instead of y.  For example, f(4) means that we should find the value of our function when x equals 4. In this case this wouldn't be considered a function because it does not include any value for x if x equaled a certain number.
