Question

(look at picture attached)

The vertex of the parabola below is at the point
(1, -1). Which of the equations below could be the equation of this parabola?



A. y = (x - 1)^2 - 1
B. x = (y + 1)^2 + 1
C. y = (x + 1)^2 - 1
D. y = (x + 1)^2 - 3

Answer 1

PLEASE I NEED HELP WITH APEX

Answer 2

it's not D.

Answer 3

it's nor b either, so im down to A or C

Answer 4

COME ON PEOPLEEEEE PLEASEEEEE

Answer 5

one sec

Answer 6

\[(y-k)=a(x-h)^2\]where \((h,k)\) is the vertex
once you plug in the points, solve for \(y\) and you'll see the answer :)

Answer 7

you should end up with:\[(y+1)=a(x-1)^2\]\[y=a(x-1)^2-1\]

Answer 8

so my abswers A!
