Answer:
Step-by-step explanation:
- Equation of (y - k)^2 = 4p (x - h), where the focus is (h + p, k) and the directrix is x = h - p
Given is the parabola:
It has a vertex at (-2, -1)
New vertex (-1, -1) requires translation to the right by 1 unit. Which changes the function to:
- (y + 1)^2 = (x + 2 - 1) ⇒ (y + 1)^2 = (x + 1)
For this function the focus and directrix is:
- (y + 1)^2 = (x + 1)
- k = -1, p = 1/4, h = -1
Focus is
Directrix is:
