Answer 1

@dude

Answer 2

Any ideas or completely lost?

Answer 3

I know that the axis of symmetry is 0.5,

Answer 4

@dude

Answer 5

i don't know high school math so I can't help :(

Answer 6

Right, the vertex is just the point on the axis of symmetry

Answer 7

vertex(0.5,0.75)@dude ?

Answer 8

-0.75

Answer 9

I mean I am not sure if it is accurate but yes it looks right
(0.5, -0.75)

Answer 10

what about the formula?

Answer 11

General formula is
\((x-h)^2+k\)

Where the vertex is (h,k)

Answer 12

(x-0.5)-0.75

Answer 13

Axis of symmetry: x = 0.5; Vertex: (0.5, –0.75); f(x) = –x2 – x – 1


Axis of symmetry: x = 0.5; Vertex: (0.5, –0.75); f(x) = –x2 + x – 1


Axis of symmetry: x = 0.5; Vertex: (0.5, –0.75); f(x) = –x2 + 2x – 1


Axis of symmetry: x = –0.5; Vertex: (–0.5, –0.75); f(x) = –x2 + x – 1

Answer 14

^^^those are the choices

Answer 15

Forgot to mention that this is negative

\(-(x-0.5)^2-0.75\)

Expand it using FOIL

Answer 16

-x^2+x-1

Answer 17

Right
