k, so a function means every x has 1 y, doesn't mean tat every y has 1 x
so
(1,2) and (1,3) is not a function
but
(1,2) and (2,2) is
the set of points is a function because no x value repeats with a differnt y value
so statement 1 is false
domain is the highest to lowest x values
but, we don't include decimals so statment 2 is false
the range is the y values
that is 6,7,8,10, repeats are ignored and written once
so this is true
statment 3 is true
