Answer 1

@wolf1728

Answer 2

What is so funny?

Answer 3

Alright

Answer 4

@wolf1728

Answer 5

Ok now what?

Answer 6

You surely want Wolf to help you, so I'll let him/her help you. (:

Answer 7

Loll I don't mind who helps me understand the question I just tagged him because he usually comes @Mikeyy1992

Answer 8

No mikeyy - you have already demonstrated your mathematical acumen and you are therefore the only person in this message board (maybe even the entire planet) that knows all the answers.

Answer 9

Lmao

Answer 10

Huh?

Answer 11

Lol, from earlier today.

Answer 12

You read earlier questions 0.o lmao

Answer 13

I was not trying to confuse anybody mikeyy - how about helping HelloGoodMorning?

Answer 14

I would, but he surely wants you to help. (:

Answer 15

Again I say I don't mind whoever helps me. You two couold even teamwork to help me for this question. My brain is very fried so I would really appreciate the help and hey @Directrix

Answer 16

I'm assuming the first question is asking if the quadratic is concave up or down.
So let's devise a quadratic equation
2x² +3 -4 =0
It is concave up (shaped like a 'U') because the 'a' term (2) is positive.

Answer 17

I guess mikeyy left.

Answer 18

Loll well then

Answer 19

The graph (being concave up) has a minimum point. (Technically it does have a maximum point - infinity).

Answer 20

Up~Minimum
Down~Maximum

Answer 21

Ok should I be putting all this inside my notebook to turn into my teacher online

Answer 22

Lol. FLVS?

Answer 23

Yup >:(

Answer 24

I did this same problem. Lol.

Answer 25

I'm so sick of flvs but I have to finish ninth grade apexvs messed me up

Answer 26

Wolf, you gave a bad equation.

Answer 27

Wait guys could you please do this step by step I need to be able to comprehend it so I can turn it in online

Answer 28

Doesn't fit the form.

Answer 29

The vertex (minimum or maximum point) is found by taking a derivative of the equation.
The derivative of 2x² +3x -4 =0 is 4x +3
so the vertex is at x = -3/4

Answer 30

Goodjob fixing your typo :P

Answer 31

Could we start over guys I'm a little bit lost.

Answer 32

Use the same equation and copy and paste what you have too just please start again

Answer 33

okay mikeyy I think HelloGoodMorning wants to see real answers here with none of this foolishness thrown in.

Answer 34

Lol.

Answer 35

He could of been done by now, if you didn't try to argue with me and change the equation.

Answer 36

You mean I could HAVE been done by now?

Answer 37

No, he could of had all the information on this question and finished it.

Answer 38

Guys no need for arguments.Lets get together and feel alright.One love .One heart. Lets get together and feel alright.EVERYBODY NOW!

Answer 39

@HelloGoodmorning I just don't want you to get bad information.

Answer 40

Why don't you just answer the question Mikey?

Answer 41

Loll I understand go on.

Answer 42

I tried too, but I left Wolf do his thing.

Answer 43

let*

Answer 44

Still explain yours I don't mind who helps me I appreciate all who helps

Answer 45

U haffi Do What You Haffi Do Fi Get Di Answer. Follow Yeh Art Bwoy , You'll Find Di Answer

Answer 46

I don't remember, I made the equation up and deleted it, because of Wolf making up his own.

Answer 47

made*

Answer 48

Maybe it was: 2x^2 + 3x + 5

Answer 49

Loll I understand go on.

Answer 50

Lmfao @sos101 leave me alone bro :p

Answer 51

Since the variable a is positive you know that it will have a minimum point.

Answer 52

Lmao @HelloGoodmorning I live with u ; I'll never leave u alone :D

Answer 53

Which concludes it will be a upward parabola.

Answer 54

Ok mikeyy could you do me a favor and explain it all in one and loll I know sos lmao

Answer 55

The vertex is: -3/4 over 4.

Answer 56

Pretty sure, you could just use -3/4

Answer 57

x- intercepts are -2 and 0.5

Answer 58

Dude could you explain it all in one you know flvs the way it goes

Answer 59

You now have all the information to need to fill out your questions.

Answer 60

All in one, so you can copy and paste. You know you need to put it in your own words, then you won't lose points or get a 0 on it.

Answer 61

Of course I have to put it in my own words but it would have been a lot easier to put it all together so I can actually understand you and then put it in my own words

Answer 62

I know this isn't my math homework, but how did you get the vertex?

Answer 63

You can just read over it, it's all right there.

Answer 64

-_-

Answer 65

I have graphing technology.

Answer 66

I will have to regardless

Answer 67

How did people do math without graphing calculators?

Answer 68

You tell me. Lol.

Answer 69

XD

Answer 70

Are you finished explaining?

Answer 71

2x^2 + 3x + 5
Since the variable a is positive you know that it will have a minimum point.
The vertex is: -3/4
x- intercepts are -2 and 0.5

Answer 72

There. Lol.

Answer 73

Lmao dude that's all I asked for

Answer 74

Lol. I put more time into this then my own exam.

Answer 75

I'm now going to put it in my own words

Answer 76

@HelloGoodmorning

From @tcarroll010

Here's one for you. See attachment.

Answer 77

@Directrix if he used that one, his teacher wouldn't give him credit.

Answer 78

Thanks Loll

Answer 79

@Mikeyy1992 does your answer explain everything up there for my question?

Answer 80

HelloGoodMorning
Attached is a graph of the function.
