What about this guy?

y = ( x + 2 )^2
 

What will make him 

y = ( 0 )^2 ?

y = ( x + 2 )^2 ... x = -2

So, start him over at x = -2 :

y = x^2

y = ( x + 2 )^2

graph of y = x^2

graph of y = ( x + 2 )^2

 

moves Standard Parabola Guy
over to
x = -2

Check out this animation to see how I work through these things:
