Answer:

The correct answer is choice D.

Step-by-step explanation:

Since the parabola opens sideways, that means the function will feature $y^2$ and not $x^2$ , so you can immediately rule out options B and C. Because the graph also opens right, that means the coefficient of $y^2$ is positive. Using all of this information, you'll find that the correct answer is D: $x = \frac{1}{12} y^2$ .
