I am beginning to work withPolynomial,Rational, andQuadraticfunctions...

I can understand most of it but I am having issues trying to understand who it works if written like this,

I am told that the first thing to do is completing the Sqr, by adding oneandsubtracting one, thus;

and so my vertex is (-1,-1)

but now how about the and the coordinates?

Thank you and sorry for such a long post.
