this is for my virtual school class. I've gone through the lesson numerous times but im still struggling, any help?
Derive the equation of the parabola with a focus at (0, 1) and a directrix of y = −1.

A.) f(x) = −one twenty-fourth (x − 1)2 − 5
B.) f(x) = one twenty-fourth (x − 1)2 − 5
C.) f(x) = −one twenty-fourth (x + 5)2 + 1
D.) f(x) = one twenty-fourth (x + 5)2 + 1

B.) f(x) = one twenty-fourth (x − 1)2 − 5
C.) f(x) = −one twenty-fourth (x + 5)2 + 1
D.) f(x) = one twenty-fourth (x + 5)2 + 1
