Answer:
Step-by-step explanation:
The standard vertex form of a quadratic (which is what your graphs are) is
where h and are the coordinates of the vertex. The vertex is really all we need to fill in this equation. Looking at the blue graph, the vertex is located at (-4, 1), so h = -4 and k = 1. Filling in the equation:
which simplifies down to
. It's that simple.I think that's choice C (I'm not sure; it's very tiny!)
