Answer:
the second one
Step-by-step explanation:
in order for it to be a function the x values CANNOT repeat.
in answer a the x value -6 repeats so that cannot be a function
in answer b none of the x values repeat so its probably this one but lets check the other ones just in case
in answer c the x value 8 repeats so it cannot be this one
in answer d the x value -2 repeats so it cant be this one \
b is the only one that does have repeating x values therefore it is the second one
