Question

Choose the graph that best represents the parabola.

x=-1/4y^2

Answer 1

One way to do this. Notice that when y=0 you get x=0. so the graph must go through 0,0
now try y=2, x will be -(1/4)*2^2 = -1/4 * 4 = -1
look for the graph where x=-1 and y=2

Answer 2

Similarly, when y = 4, x = -4, so you can look for that point also. :-)

Answer 3

so would it be the second one?

Answer 4

hard to pick out the details on it, but yes, that does seem to fit the bill
