Answer :
Answer:
the second set, {(-5,6), (9,4), (-7, 2), (-9,6)}
Step-by-step explanation:
a function is when the domain has only one range, in all the sets there are multiple domains (x) with diff ranges (y), but not in the second one.
There is a rule for functions:
One input(x-value) can only have one output(y-value).
If one input has more than one output, it is not a function.
(This doesn't apply to outputs, one output can have more than one input and still be a function)
(0,1), (2, -1), (-7,6), (0,3)}
This isn't a function because the input 0 has more than one output of 1 and 3
{(-5,6), (9,4), (-7, 2), (-9,6)}
This is a function because each input has only one output.
{(6, -6), (-7,8), (9,3), (9, –5)}
This is not a function because the input 9 has more than one output of 3 and -5
{(–2,1),(-1,-9), (-2,-6), (2, -2)}
This is not a function because the input -2 has more than one output of 1 and -6
