The circle could've been done in one equation
One equation, sure, but not in one valid function (without making it parametric anyways)
x^2^+y^2^=1
or, in this case
(x-2)^2^+(y-2)^2^=1
Not valid functions
A valid function needs to pass the vertical line test
Ok you're right
A that's a single equation alright. But as the previous poster pointed out, it's not a function.
