The graph is a parabola with a minimum point, and opens upward, indicating a positive leading coefficient. This can be determined by the equation being in the form of $y = ax^2 + bx + c$, where $a > 0$, $b = 2$, and $c = 0$. The vertex can be found by completing the square or using the formula $(-b/2a, f(-b/2a))$. The vertex is $(-1, -1)$, and the y-intercept is $y = 0$. Therefore, the best choice is B.
