Question

What is the equation of the quadratic graph with a focus of (4, −3) and a directrix of y = −6?

f(x) =negative one over six times x squared plus four over three times x plus eleven over six
f(x) =one over six times x squared minus four over three times x minus eleven over six
f(x) = three fiftieth x squared plus eleven twenty fifth x plus three fifth
f(x) = two fiftieth x squared plus eleven twenty fifth x plus two fifth
