Question

Determine whether the relation is a function.

{(-5, -4), (-2, 9), (-1, -2), (-1, 7)}

Answer 1

is there any other functions ?

Answer 2

No

Answer 3

i don't think its a function

Answer 4

because -1 cant have a different answer no matter the function you have.

Answer 5

its not a function because the x is repeating, if you see the same number for x twice, then it is not a function. In your problem, -1(which is the x value) is repeating twice (-1,-2)(-1,7) so it is not a function.

Answer 6

no its not bc there are 2 of the same x values, there is two -1 therefor it doesnt make it a function
