Which equation has a graph that is a parabola with a vertex at (–1, –1)?
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:

Which equation has a graph that is a parabola with a vertex at (–1, –1)?

using the formula for vertex form

y = a (x- h)^2 + k

get

y = a (x - (-1))^2  - 1

y = a (x + 1)^2  - 1

choose the last one

y = (x + 1)^2  - 1

the one that has a slope of 1/2 and is positive.
