How do you determine what could represent a function in algebra

Hi, here is my
First, if you want to determine that's relation is function, you have to realize that your value of x(Domain) is not repeated.= so, it's a function
But...If your value of x (Domain) is repeated twice or more, so I can guaranteed that is totally NOT a function

Hi there! To answer your question or more questions like these you'd want to determine that relation is function, the value of x which would be your base or domain is not repeated, so by using this guideline you can determine if it's a function. On the other hand, if your value of x is repeated twice or more (+), it isn't a function. Hope this helps you and remember to mark as brainliest! BTW I like the question. It made me think a lot. :)
