You did not show or reference to the pictures to choose.

Assuming you mean, x%5E2%2B+8x+-+y+%2B+2+=+0, putting into general form becomes y=x%5E2%2B8x%2B2

Parabola with axis parallel to the y axis, with a minimum point, and should have two x intercepts. Vertex about (-4,-14).

Discriminant is 8%2A8-4%2A2=56;
a=1
