Ghoulie · Answer 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

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