What is an equation for the parabola with focus (0, -12) and directrix y = 12

Given:

Focus of a parabola is (0, -12) and directrix is y = 12.

To find:

The equation of the parabola.

Solution:

General form of a parabola is

      ...(i)

where, (h,k) is vertex, (h,k+p) is focus and y=k-p is directrix.

Focus is (0, -12).

        ...(ii)

Directrix is y = 12.

     ...(iii)

Adding (ii) and (iii), we get

Putting k=0 in (ii), we get

Putting h=0, k=0 and p=-12 in (i).

Therefore, the required equation of parabola is .

in mathematics, a function is a relationship between two variables such that the value of one of the variables, called the dependent variable, is determined by the value of the other variable, called the independent variable. there is a specific term we use to describe the set of independent variables of a function.
