Question

Graph one of your 2nd degree functions from question 1. Identify which function you used and the key features of your graph. Explain how to find them algebraically.

Answer 1

Your friend runs up to you, scared that he is not ready for the upcoming quadratics test. To help him study, you will create four different quadratic functions. Then demonstrate to him how to rewrite each function as a group of factors, if possible.
The function f(x) is a difference of squares.
The function g(x) is a sum of squares.
The function h(x) is a perfect square trinomial.
The function j(x) can only have a GCF factored out of it.
The function f(x) is a difference of squares.
say a -b where a and b are squares
(sqrta - sqrtb)(sqrta + sqtb)

The function g(x) is a sum of squares.
does not factor

The function h(x) is a perfect square trinomial.
this has form a^2 + 2ab + b^2
factors to (a+b)^2

Answer 2

That is #1 .

Answer 3

It's okay c:

Answer 4

@Hayhayz Have you done this by any chance in your math class? Module 3?

Answer 5

Im bad at math lol @TheSmartOne

Answer 6

It's always the one I tag you in and need help with lol :3

Answer 7

@Mehek14 @Luigi0210 @ganeshie8 @KendrickLamar2014 @jabez177 @perl Can one of you help her?

Answer 8

Example: For #1
\[f(x) = x^2-9 \]
\[f(x) = (x+3)(x-3) \]

\[f(x) = x^2 + 9 <-- this ~ cannot ~ be ~ factored \]

\[f(x) = x^2 + 6x + 9 \]
\[f(x) = (x+3)^2 \]

\[f(x) 2x^2 + 2x + 2 \]
\[f(x) = 2(x^2 + x + 1) \]

Answer 9

well this is the question I posted number one because he had to do with number one ..
Graph one of your 2nd degree functions from question 1. Identify which function you used and the key features of your graph. Explain how to find them algebraically.

Answer 10

I dont understand...

Answer 11

the question i need help with is
Graph one of your 2nd degree functions from question 1. Identify which function you used and the key features of your graph. Explain how to find them algebraically.

Answer 12

Well lets go step by step.
1. Which one do you want to graph?
2. What function did you use?
3. What are the key features in your graph (once graphed)
4. How did you find them algebraically?

Answer 13

1. function h(x)
The function h(x) is a perfect square trinomial.
this has form a^2 + 2ab + b^2
factors to (a+b)^2

is this what you wanted to know?

Answer 14

Yes, that is.

Answer 15

So what do I do next I don't know how to answer the question lol am I supposed to graph something?

Answer 16

Yes, you need to graph one of your 2nd degree functions. Which one do you want to graph?

Answer 17

2nd degree functions? could I graph any of the ones from #1 or the h(x) one?

Answer 18

See, that's what im confused. Can you show me what was question 1 and your answer for that question?

Answer 19

Your friend runs up to you, scared that he is not ready for the upcoming quadratics test. To help him study, you will create four different quadratic functions. Then demonstrate to him how to rewrite each function as a group of factors, if possible.
The function f(x) is a difference of squares.
The function g(x) is a sum of squares.
The function h(x) is a perfect square trinomial.
The function j(x) can only have a GCF factored out of it.

The function f(x) is a difference of squares.
say a -b where a and b are squares
(sqrta - sqrtb)(sqrta + sqtb)

The function g(x) is a sum of squares.
does not factor

The function h(x) is a perfect square trinomial.
this has form a^2 + 2ab + b^2
factors to (a+b)^2

The function j(x) can only have a GCF factored out of it.
this has form ax^2 + abx + ac
factors to a(x^2 + bx + c)


That is the question and my answer is it wrong?

Answer 20

Ahh okay. So im guessing your answer is: The function f(x) is a difference of squares.
say a -b where a and b are squares
(sqrta - sqrtb)(sqrta + sqtb)

The function g(x) is a sum of squares.
does not factor

The function h(x) is a perfect square trinomial.
this has form a^2 + 2ab + b^2
factors to (a+b)^2

The function j(x) can only have a GCF factored out of it.
this has form ax^2 + abx + ac
factors to a(x^2 + bx + c)

Answer 21

Am I right?

Answer 22

yes is it wrong?

Answer 24

I already looked at that c: someone sent me that link for #1 I need help on #4 :) which is Graph one of your 2nd degree functions from question 1. Identify which function you used and the key features of your graph. Explain how to find them algebraically.

Answer 25

Oh okay, let me see what I can find.

Answer 26

c: Thank you

Answer 27

@Adrianna.Gongora I am going to have to go offline. I need to go pickup my cousin from school. Sorry to leave but I hope @I<3U can help you.

Answer 28

It's okay c: no problem thank you @KendrickLamar2014 c:

Answer 29

:)

Answer 30

Alright, so what are we going to graph @Adrianna.Gongora

Answer 31

That's what I am trying to figure out ;-;

Answer 32

Well what are your functions that you answered in question #1?

Answer 33

The function f(x) is a difference of squares.
say a -b where a and b are squares
(sqrta - sqrtb)(sqrta + sqtb)

The function g(x) is a sum of squares.
does not factor

The function h(x) is a perfect square trinomial.
this has form a^2 + 2ab + b^2
factors to (a+b)^2

The function j(x) can only have a GCF factored out of it.
this has form ax^2 + abx + ac
factors to a(x^2 + bx + c)

Answer 34

Alright, so which one do you want to graph?

Answer 35

Which one would be easier?

Answer 36

Hmm the last two are pretty simple to graph. Lets graph: a(x^2 + bx + c)

Answer 37

http://prntscr.com/auswlo

Answer 38

is that the graph for it?

Answer 39

Yes, that is

Answer 40

is that all I needed for #4?

Answer 41

No, you also need to: Identify which function you used and the key features of your graph. Explain how to find them algebraically.

@KendrickLamar2014 explained to you the steps to solve problem #4

Answer 42

Example: For #1
f(x)=x2−9

f(x)=(x+3)(x−3)


f(x)=x2+9<−−this cannot be factored


f(x)=x2+6x+9

f(x)=(x+3)2


f(x)2x2+2x+2

f(x)=2(x2+x+1)

this ?

Answer 43

No, this: Well lets go step by step.
1. Which one do you want to graph?
2. What function did you use?
3. What are the key features in your graph (once graphed)
4. How did you find them algebraically?

Answer 44

Okay so I would put
1. a(x^2 + bx + c)
2. Polynomial Function
3. what do they mean by this one for number 3?
4.

Answer 45

Im trying to solve #3, im not sure what they mean by "features". #4 is asking you to show the steps you took to get: a(x^2 + bx + c)

Answer 46

Okay so I would put
1. a(x^2 + bx + c)
2. Polynomial Function
3.
4.The function j(x) can only have a GCF factored out of it.
this has form ax^2 + abx + ac
factors to a(x^2 + bx + c)

Answer 47

Yes, I cant figure out what they mean by "features" ;-;

Answer 48

okay :) can you help me with one more?

Answer 49

I need to finish a Biology assignment first. I had only time to help you, then im going to do my work. When im done, ill help you :)

Answer 50

Okay :)
