$y=(x-1)^2-2$
(Graph below)

Explanation:

$y=x^2-2x-1$
Since this does not factor, you can put this into a more graph-friendly equation by completing the square.
$y=x^2-2x-1$
$y=(x^2-2x+1)-1-1$
$y=(x-1)^2-2$
The graph of this is a parabola with a vertex at $(1,-2)$ and a "slope" of 1. graph{(x-1)^2-2 [-10, 10, -5, 5]}
