Question

What are the coordinates of the vertex of the graph of the function y = –x² + 6x –11?

Answer 1

(3, –2)
(3, 16)
(–3, –29)
(–3, –20)

Answer 2

well i dont know for sure but here my opinion answer (-3,-29)

Answer 3

im 50% sure

Answer 4

dont take my word completely

Answer 5

Bring the right hand side to the form of a square(a^2 +2ab + b^2). For that you will need to multiply with equation with -1 to remove the - sign before x^2. Do that first, add 9 to both sides. Make it a square.
The vertex of a parabola:
\[(x-a)^{2}=k(y-b)\], is (a,b). Do, I need to show the steps?

Answer 6

the correct answer is 3,-2
