This parabola has a vertex at (-2, 1) and opens to the right. Therefore, the general equation will be (y - 1)^2 = 4c(x + 2). Simplifying:
(1/4c)(y - 1)^2 - 2 = x
c is a constant, which we do not need to solve for here. We just need to look at the format of the equation, which has (y-1)^2 and -2. This only fits choice C.
