What value of k will make this relationship NOT a function? {(-7, 2), (-1,0), (4,8), (k, 0)}
A) 2
B) -7
C) 8

the correct answer is b.

Step-by-step explanation:

it is b because if you plug in -7, two of the x-values will have -7 making the x-values the same and in order to be a function all x-values have to be different.

the answer is b.

step-by-step explanation:

identity property is where 0+whatever number=whatever number. basically 0+ a number.

the function makes a strait line horizontally with no x intercept but a y intercept at 9.
