Ответ:
D
Step-by-step explanation:
A has -1 going to two different y values so it is not a function
B has x = -1 going to two different y values so it is not a function
C has the input of 3 going to two different y values so it is not a function
D each input goes to only 1 output so it is a function
Ответ:
Hey there! I believe the answer would be choice D. because it is the only choice that has one input for each output.
Hope this helps!
Have a wonderful day!
