Question

Write the equation of a parabola with a vertex at (-5, 2) and a directrix y = -1.


Options are:

y minus 2 equals one-twelfth times the quantity x plus 5 squared

y minus 2 equals one-fourth times the quantity x plus 5 squared

y plus 2 equals one-twelfth times the quantity x minus 5 squared

x plus 5 equals negative one-twelfth times the quantity y minus 2 squared

Answer 1

Answer:

First one

Step-by-step explanation:

(x - h)² = 4p(y - k)

(h,k) = (-5,2)

p = 2 - -1 = 3

(x - -5)² = 4(3)(y - 2)

(x + 5)² = 12(y - 2)

y - 2 = (1/12)(x + 5)²
