The parabola has been reflected across the x-axis, so C and D are not correct already. All you have to do now is look at the numbers inside the formulas. B is the one that has the correct numbers and in the correct order. The formula is supposed to have the coordinate numbers within it (3,2). The vertex in choice A is (-2,2).
The answer is d) 14. Attached is a screenshot of how to do this on a graph. Graph the given point (5,12). Count out your slope on either side until you reach your given y value (6).
