We need to write the equation in its vertex form so we have to know the general equation for the vertex form. It is written as:
y = (x - h)^2 + k
where h and k represents the point of the vertex.
We go as follows:
y = (x^2 + 4x) – 3
y +4= (x^2 + 4x+4) – 3
y = (x + 2)^2 - 7
Therefore, the correct answer from the choices is option B.
