**Reiny**, Sunday, December 16, 2012 at 10:52pmchange it to the standard form

y = a(x-p)^2 + q , by completing the square

y = x^2 = 4x

= x^2 + 4x**+ 4 - 4**

= (x + 2)^2 - 4

All the above can now be answered readily.

The form y = a(x-p)^2 + q

should be in your text or in your notes from class.
