Just checking my work:
Find the equation of the parabola with vertex at the origin, that passed through the point (-6,4) and opens upward.

I came up with y=1/9x^2

Am I right?

You can check yourself. If the graph goes through (-6,4), it means that when you put x=-6 into the equation you should get y=4. Is that the case?
