Question

Hi

Answer 1

@jim_thompson5910

Answer 2

well y = -(x+1)^2+9 is practically in vertex form already

do you see how?

Answer 3

no

Answer 4

y = -(x+1)^2+9

is the same as

y = -1(x- (-1))^2+9

see it now?

Answer 5

yeah

Answer 6

whats next

Answer 7

compare it to y=a(x-h)^2+k

Answer 8

tell me what a, h, k are equal to

Answer 9

a=-1 h=1 k=9

Answer 10

@jim_thompson5910 what do I do next

Answer 11

@charlotte123

Answer 12

@MayMay_69 didn't study this yet D: try wolframalpha ^-^

Answer 13

I can't find him can you tag him for me

Answer 14

h=-1, a=-1, k=9

Answer 15

@wio your pic is so cute ^O^

Answer 16

It already is in vertex form.

Answer 17

Thanks @charlotte123

Answer 18

really?

Answer 19

Yes.

Answer 20

okay what about this one, y=(-x+10) (x+2)

Answer 21

First expand it out. Can you do that?

Answer 22

No sorry

Answer 23

could u help me please

Answer 24

@Mertsj

Answer 25

The requirement is that you write each problem in vertex form.

Answer 26

Then the problem tells you that vertex form is y = a(x-h)^2+k

Answer 27

So your job is to make each equation look exactly like that.
