Answer:
The vertex form would be y = (x+2)^2
The factored form would be y = (x-2)(x-2)
The standard form would be y = x^2-4x+4
Step-by-step explanation:
To find this, you know that the vertex is 2 left from the center, so you have h = -2, and k = 0 since it isnt shifted up. The graph isn't shifted up either, so a=1.
The vertex form would be: y = a(x-h)^2+k
= (x+2)^2
The factored form would be y = (x-2)(x-2)
The standard form would be y = x^2-4x+4
