Can someone help

Answer 3

Pretty straightforward

It's a quadratic equation so it's going to be in the form of

y = (x-h)^2 + k

where (h,k) is the vertex

Answer 4

What is the vertex in your drawing? @NevaehJade6219

The vertex is the pointy point of the graph

1?

Answer 7

It should be a point

(x, y)
x value, y-value

oh -1,-6

Answer 9

there you go

Answer 10

so remember, I said (h, k) is the vertex in y = (x-h)^2 + k

so you said the numbers are (-1, -6)

so h = -1
and k = -6

can you put that into

y = (x-h)^2 + k

Answer 11

ok y=(x-1)^2+-6?

Answer 12

no

Answer 13

uhh check inside the parenthesis

what happens when we're subtracting a negative number

here's an example for you

2 - (-2) = 2 + 2

oh yea sorry. y=(x(-1))^2+(-6)?

Answer 15

no

Answer 16

also pls don't quote/tag me in each reply, I already get a notification when you respond

Answer 17

so

y = (x - (-1)) ^2 + (-6)


what is
x - (-1)

Answer 18

look at the example I gave you

2 - (-2) = 2 + 2

Answer 19

so h = -1
and k = -6
can you put that into
y = (x-1)^2 + (-6)

Answer 20

srry i copy and pasted

Answer 21

y = (x-1)^2 + (-6)

Answer 22

no

Answer 23

what did we say about

It's

(x - h)

we said h is -1

so what is x - (-1)

we need to get rid of these + -
can't have two of them next to each other

Answer 24

x-1

Answer 25

NOOOO

Answer 26

😭

Answer 27

negative and negative is positive
positive and negative is negative

Answer 28

look at my EXAMPLE

x - (-523)

x minus NEGATIVE 523

will be the same thing as

x + 523
x PLUS 523

Answer 29

so what is

x - (-1)

Answer 32

x is a letter

it's a variable, it's used to represent any possible number that it could stand for

Answer 33

now at this point i forgot what you wanted me to do

Answer 34

We have y = (x - (-1)) ^2 + (-6)


Do you see how we have the - and then again -

when you see that, it becomes a +

5 - (-5) = 5 + 5

similarly
x - (-3) = x + 3

so in our question, we have
x - (-1)

what is it??

Answer 35

x+1

Answer 36

YAY

Answer 37

🥺

Answer 38

yes!! okay but don't get too excited, we still one last thing

now we have

y = (x +1) ^2 + (-6)


do you see that
something + (-6)

so an example:

4 + (-3) = 4 - 3

51 + (-4) = 51 - 4


so

y = (x+1)^2 + (-6)

what would it be

Answer 39

maybe a very much similar example

y = (x+1)^2 + (-73)

it would be
y = (x+1)^2 - 73

so now your question is

y = (x+1)^2 + (-6)
what would it be?

Answer 40

(x+1)^2-6?

Answer 41

tada!

Answer 42

ok. thank you again..

Answer 43

You're welcome!

Answer 44

it says i got it wrong

Answer 45

oh they want you to expand it too

so do you know

(a+b^2 = a^2 + 2ab + b^2

how would you expand
(x+1)^2 =

Answer 46

or if you do the FOIL method

(x+1)(x+1) =

Answer 47

wait

Answer 48

can we do the foil method

Answer 49

wait? ok.

Answer 50

so we forgot a value on the outside

y = A(x+1)^2 - 6

you see how they gave us that second point on your graph of (-2, -3)

we need to plug in (-2, -3) and solve for that A

so

-3 = A(-2 + 1)^2 - 6

so what is -2 + 1 =

Answer 51

-1

Answer 52

good and what is (-1)^2

or basically what is
-1 * -1

Answer 53

-1

Answer 54

no just 1

Answer 55

yes, it's just 1

so now we have

-3 = A - 6

what is A?
add 6 to both sides

Answer 56

what is -3 + 6

Answer 57

+3

Answer 58

good so that means A = 3

so the equation is

y = 3(x+1)^2 - 6

Answer 59

hopefully that's an acceptable answer and they don't want you to like expand it

Answer 60

correct! WOOPIE!! thanks!

Answer 61

Yay :D
