I think you mean "quadratic function." That's because \ =\ x^2\ -\ 2x\ -\ 35)
, is, in fact, a quadratic function. The Quadratic Formula is something else entirely.
Given a quadratic function of the form: \ =\ ax^2\ +\ bx\ +\ c)
The 
-coordinate of the vertex is 
. The 
-coordinate of the vertex is the value of the function at that -value.
So: }{2(1)}\ =\ 1)
, and \ =\ (1)^2\ -\ 2(1)\ -\ 35\ =\ -36)
. Hence the vertex is at )
