Thank you for the opportunity to help you with your question!

y=2/5x^2......................................................................Not a function

y=6x.......................................................................function

y=2x+6..................................................................function

y^2= - 2x ..........................................................not a function

All function equations must follow thje rule of y=mx+c where m is the gradient and c=y intercept

Neither x nor Y should be a squared value in a fuction equation

Please let me know if you need any clarification. I'm always happy to answer your questions.
