Question

alg 2 help? pleasee. ill fan & medal you :)

Answer 1

Create a quadratic function, f(x), in vertex form. The a should be between 4 and –4, the h will be your birth month, and the k will be your birth day. Write your equation below.

Using complete sentences, explain how to convert your birthday function into standard form.

Create two additional quadratic functions, g(x) and h(x).
The function g(x) will open the same direction as f(x), have the same vertex, but will be narrower.
The function h(x) will open in the opposite direction as f(x), have the same vertex, but will be wider than f(x).
Write your functions below and explain in complete sentences why those functions will meet the requirements in the question.

Graph your functions. Include your graph below.

Using complete sentences, explain how to find the average rate of change for f(x) from x = 4 to x = 7.

Explain the appropriate translations of your graphs, if you were born two months earlier and 5 days later. Use complete sentences.

Answer 2

my birthday is 02 09 :))

Answer 3

@jojo7 @math&ing001 are you guys going to help me?

Answer 4

I'll see what I can do.

Answer 5

thank youu<3333

Answer 6

Do you know what the vertex form is ?

Answer 7

Can you help me @math&ing001 when you are done here?

Answer 8

Ok

Answer 9

<------ My question is the third on the list

Answer 10

No i dont :/ lol.

Answer 11

@kendallnicole this is the vertex form of a parabola y=a(x−h)^2+k
Now all you need to do is replace h will be your birth month and k with your birth day. You can choose a randomly between 4 and -4.

Answer 12

so that is for number 1?

Answer 13

Yeah !

Answer 14

thanks!:) number 2?

Answer 15

Distribute the function you got before to get it to standard form.

Answer 16

can you show me?:(

Answer 17

Ok show me what you got for the function.

Answer 18

y=1(x−2)^2+9

Answer 19

that?

Answer 20

Yeah ! Now use this formula (a-b)^2=a^2-2ab+b^2 to get it to standard form.

Answer 21

Thanks<333333

Answer 22

yw

Answer 23

can you explain how to get it back in standard form? like i understand it, but i have to say it in complete sentences.

Answer 24

To convert equation to standard form we simply expand and simplify the binomial square.

Answer 25

Thanks!!! can you help me with #3?

Answer 26

Sure ! For g(x) to be narrower than f(x), you need to choose a bigger 'a'. For h(x) to be wider keep the same vertex and choose 'a' smaller but positive like (0.5 or 0.25...)

Answer 27

THANK YOU YOURE SAVING MY LIFEEEE

Answer 28

can you show me how to graphit?!

Answer 29

Answer 30

@math&ing001

Answer 31

Vertex form makes it easier to graph a parabola
