PLZ HELP HURRY PLZ WHOEVER GETS IT GETS 30 POINTS

In the explanation. :)

Step-by-step explanation:

Th answer is D. Simply because when you have a function the Input needs to be paired with exactly one output. 2 inputs can not be paired together, if you want it to be a function. It would also be nonlinear because if you graph it, it would not be in a straight line.

Hope this helps. Have a great day.
