Answer:
y = (x + 1)² - 1
Step-by-step explanation:
The equation of a parabola in vertex form is:
y = a(x - h)² + k
where the vertex is located at (h,k). Replacing with vertex at (-1, -1) we get:
y = a(x - (-1))² + (-1)
y = a(x + 1)² - 1
The only option with vertex at (-1, -1) is y = (x + 1)² - 1 (where a = 1)
