URGENTThe point (0, -9) is the focus of the parabola shown What is the equation of the parabola? y=1/36x^2 y=1/9x^2 y=-1/36x^2 y=-1/9x^2
Question
Answer:
The function of the parabola can be expressed as :(x - h)^2 = 4p (y - k)
Where the coordinate of the focus is (h + p, k) , the vertex (h,k) and the distance between the focus with the vertex is p.
The distance of focus and vertex would be -9-0=-9
Then the equation would be:
(x - h)^2 = 4p (y - k)
(x - 0)^2 = 4*-9 (y - 0)
x^2= -36y
y= -1/36 x^2
