Question

Axis of symmetry got cut off

Answer 1

first draw a vertical line that divides the graph into two equal halves

Answer 2

the line would be in the middle right

Answer 3

good, now identify the x-value of that line

Answer 4

-2.5

Answer 5

actually 0

Answer 6

oh i accidently put the line on the 0 axis

Answer 7

from that it would be -1

Answer 8

good so the axis of symmetry is x = -1

to find the vertex we simply find the value of the graph at x = - 1

Answer 9

-3.5?

Answer 10

(-1,-3.5)

Answer 11

good, that's the vertex

Answer 12

to find the intercepts simply find the x-values where y = 0 and the y values where x= 0

Answer 13

***actually I believe the vertex is (-1,-4) the axis isn't drawn well

Answer 14

since it's 4 spaces below 0

Answer 15

so (0,0)(1,0)(2,0)(3,0)(-1,0)(-2,0)(-3,0)(-4,0)

Answer 16

how are you getting these numbers

there are only two x-values where y = 0

Answer 17

ohhh where it intercepts duh

Answer 18

sorry

Answer 19

(1,0)(-3,0)

Answer 20

good, now what is the value of y when x = 0?

Answer 21

-2.5

Answer 22

(0,-2.5)

Answer 23

I think it's (0,-3) since each space is meant to represent 1 unit

Answer 24

So there would be three sets of intercepts (1,0)(-3,0)(0,-3)

Answer 25

yes

Answer 26

oh it isn't 2.5

Answer 27

I thought it was

Answer 28

yeah, each space is 1 unit and it's 3 units below y = 0

Answer 29

Intercepts : (1,0)(-3,0)(0,-3)
Vertex: (-1,-4)
Axis of symmetry : x=-1

Answer 30

well done

Answer 31

I need to go to a meeting, be back in a few hours

Answer 32

Sounds good =)
