Which equation has a graph that is a parabola with a vertex at (-1, -1)? ОООО
O y = (x - 1)2 + 1
y = (x - 1)2 - 1
y = (x + 1)2 + 1
· y = (x + 1)2 - 1

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)
