Answer:


x^(2) =3y

Explanation:

Notice that the focus is a points on the vertical axis, that means the parabolla opens vertically, and has the form


x^(2) =4py

Because the parameter
p is positive and equal to 0.75. Additionally, the vertex is at the origin, that's why the equation is this simple.

Replacing the parameter value, we have


x^(2) =4(0.75)y\\x^(2) =3y

Therefore, the equation of a parabolla with vertex at the origin and focus at (0, 0.75) is
x^(2) =3y.
