how would i go about graph sketching the equation...

$\displaystyle y=x^2+2x+4$

The book i'm reading just kind of threw this one in the problem set without explaining it. I usually use the parent function to graph the "child equation." i'm not sure what the parent function of the equation is. The book i am studying does not explain how to graph polynomials like this.

thanks!

edit: i tried to factor the equation (x+_)(x+_) but couldn't figure it out that way.
