Question

What is the vertex of the parabola given by y = -(x − 2)2 − 1?

(2, 1)

(2, -1)

(-2, 1)

(-1, 2)

Answer 1

\[y = ax ^{2} + bx + c.\]

thats how you find the vertex
now make your equation into a proper equation.

Answer 2

is it meant to be \[-(x-2)^{2}\]

Answer 3

whats the answer?

Answer 4

you need to answer my question first so i can figure it out

Answer 5

yes

Answer 6

\[(x-2)(x-2)=x ^{2}-4x+4\]
\[-(x ^{2}-4x+4)2-1\]
\[-x ^{2}+4x-2\]
go from there and do the rest of the equation when you have a full equation the first spot is a second is b and third is c plug it in to the first equation i gave you and you'll have your answer
