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

See below.

Step-by-step explanation:

The vertex form of a parabola is

y = a (x - b) ^2 + c where (b, c) is the vertex so when the vertex is (-1, 1) the equation is

y = a (x + 1) ^2 - 1.

where a is some constant.

Is there a list to choose from?
