Answer:
A) domain-(2,3,4,5,6)
range- (2,3,4,5,6)
A=function and passes the vertical line test
B) domain-(-5,-3,-1,1,-1)
range- (1,-1,-3,-5,7)
B= not a function it doesn't pass the vertical line test
Explanation:
the domain is the X's or the first number in the line and the range is always the second number A is a function because none of the domains repeat for example there is only one two in a and there is only one three in a if there were two threes then it would have not been a function like B there are two negative ones in the domain and because there are two negative ones in the domain it is not a function and it doesn't pass the vertical line test
