Which of the following equations will produce the graph shown below..

Answer:
D) x - 1/8y² = 0
Step-by-step explanation:
This resembles a parabola, but turned on its side.
A parabola is the graph of a quadratic equation, in the form y = x².
Since it is turned on its side, it must be an equation of the form x = y²; the only equation with a y² term is D.
