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

3 x^2 - 9y + 6 = 0

Put the equation in terms of y equal to a function of x:

9y = 3x^2 + 6

Divide by 9:

y = 1/3x^2 + 2/3

Clearly this is not a linear function because x is squared.

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