Question

Find the equation of the axis of symmetry and the coordinates of the vertex of the graph of each function.
6. y = x^2 - 6x + 4

Answer 1

@faith2012

Answer 2

The equation for the axis of symmetry would look like x=-b/2a

Answer 3

thats the answer?

Answer 4

No, that's the formula to get the axis of symmetry

Answer 5

whats the answer tho? ;/

Answer 6

Do you know how to factor?

Answer 7

yeah

Answer 8

Factor the equation

Answer 9

(x-_)(x-_)

Answer 10

So you already have the answer for the vertex

Answer 11

what about the coordinates and axis of symmetry?

Answer 12

The axis of symmetry is 3

Answer 13

thats all i need to write down?

Answer 14

x=3

Answer 15

So I write '' Vertex : (3. -5) & Axis of symmetry: x = 3'' ? @faith2012

Answer 16

Yes

Answer 17

Vertex: (3, 5), Axis of symmetry: x=3

Answer 18

yay thank you sm! (: what about 7. y = 4x^2 + 8x + 7? :)

Answer 19

Axis of symmetry is -1

Answer 20

wait is the vertex on the last one (3,5) or (3, -5)?

Answer 21

I mean on the first one^^

Answer 22

Oops, it's (3, 5)

Answer 23

not negative?

Answer 24

No.

Answer 25

oh ok whats the vertex of the last one?

Answer 26

(-1, 3)

Answer 27

tysm (: <3
