All x not equal to 0! right you are sir! And do you know why?

If than working backwards So if than how is it that ?
not possible to /0?
In basic arithmetic division by zero is meaningless. So for a function like , we simply say that @ x = 0, y is undefined. This is also the case in your original equation.
How can you divide by nothing? See what I'm driving at?
i think the domain would be x
Yes, the intent was for what values of our domain is our range defined.
