(adsbygoogle = window.adsbygoogle || []).push({}); 1. X^2 + y = 8

2. Relevant equations

3. my steps:

y = 8 - x^2

x^2 = 8 - y

(8-y) + y = 8

Not a function.

My logic is, because the equation does not equal y, it is not a function

Please show me step by step the right answer, and preferably the reason why.
