Which is the equation of the parabola?
Umnica [9.8K]

Answer: y=-\dfrac{1}{8}(x - 2)^2 - 3

<u>Step-by-step explanation:</u>

The vertex form of a parabola is: y = a(x - h)² + k    where

  • (h, k) is the vertex
  • a=\dfrac{1}{4p}  

NOTE: p is the distance from the vertex to the focus

The vertex (h, k) is (2, -3)

p=-2\quad \implies\quad a = \dfrac{1}{4(-2)}=-\dfrac{1}{8}

Insert those values into the vertex formula to get:

y=-\dfrac{1}{8}(x - 2)^2 - 3
