Graph the quadratic equation...

I really need some help here. Please be specific as this is new to me.

Graph the quadratic equation after completing the given table of values.

*y* = *x^*2 + 2*x* – 3.

*Include the axis of symmetry and show specific points, vertex, and intercepts.*

*x, y*

*–3, ?*

*-2, ?*

*–1, ?*

*0, ?*

*1, ?*

I don't expect anyone to try to tell me how to graph the points. I can do that. I need step by step with how to get the points, axis of symmetry and vertex. My text doesn't really help me understand and this is the only problem I can't figure out of my assignment.

Greatly appreciated!! :(:confused::(:confused:
