Question 372640: WHat is the graph for this equation?

f(x)= x^2+6x+8
I'm not sure if the quadratic equation is used for this or factoring?. i used h=-b/2a to get h,k = (-3,-1) but i'm not sure if that is what i am supposed to do. The graph is supposed to be a parabola i believe. I need to find the points for it. Please help!
