Answer:
[tex]y=\dfrac{1}{36}x^2[/tex]
Step-by-step explanation:
Where p is the distance from focus to vertex, the equation of the parabola with focus at (0, p) is ...
[tex]y=\dfrac{1}{4p}x^2[/tex]
Your parabola has p=9, so the equation is ...
[tex]y=\dfrac{1}{4\cdot 9}x^2=\bf{\dfrac{1}{36}x^2}[/tex]
