I need a help here , I can't understand it
Q- Which relations define y as a function of x?
1) 3x - y^2 + 4=0
2) y= 4x + 2
No, the only way though this is for you to understand how to solve this problem. First, you need to understand what a relation and a function are and be able to give examples of relations that are functions as well as relations that are not functions. Then you can follow Quacky's advice.
Feel free to ask any questions.
