The proper graph is on graphcd.jpg.

- anonymous

So the second attachement, first image.

- anonymous

Oh okay, but i got a different answer on my graph cal. I feel like its messed up or something

- anonymous

Make sure you put parentheses.

- anonymous

Actually, wait one sec.

- AravindG

i can lend you my graphing calculator
http://www.wolframalpha.com/

- anonymous

Aww thanks @AravindG

- AravindG

yw :)

- anonymous

On the first attachement, is there an intersection at y=-10?

- anonymous

It looks like the first attachement, graph 2.

- anonymous

@zordoloom I think its under the -10, but it is by it. & im checking in my cal. now

- anonymous

Okay, Its the on the first attachement, graph 2 then.

- anonymous

How did you get that answr ?

- anonymous

I graphed the graph and found its derivative. And it has an intersection below -10.

- anonymous

oh okay so if we look back is my answer A ?

- anonymous

No

- anonymous

:( What is it ?

- anonymous

I think it would be b. Because its the second graph on the first attachment. They aren't lettered, so I don't really know.

- anonymous

Ill show you one at a time.

- anonymous

Yeah thats b Are you 100% sure ?

- anonymous

I'm about to try and graph it one more time

- anonymous

Yes, Positive.

- anonymous

Thankyou. Do you think you can help me with another problem im having trouble with ?

- anonymous

Sure.

- anonymous

So, was it correct?

- anonymous

- anonymous

Give me a moment.

- anonymous

Okay, it's either the first one, or the third one.

- anonymous

How do you know that ?

- anonymous

Take the limit as x goes to 0.

- anonymous

Is this by any chance calculus?

- anonymous

No

- anonymous

Its the first one.

- anonymous

I still don't understand lol How did you get that ? can you please show me.

- anonymous

Have you studied limits?

- anonymous

Yes i took notes & i'm looking over them now, but i just need just a little help of how you got that.

- anonymous

are you 100% sure its the first one.

- anonymous

Sure. So you start by multiplying everything out. Then canceling like factors and you get the first and third choice.

- anonymous

Yes, 100%.

- anonymous

So the only option left is the first one.

- anonymous

Im working out the problem. & thank you :)

- anonymous

Another easy way to figure this out really fast is by looking at the options that are give. You can then determine that the only possible restriction is x can't equal 1. Everything else works.

- anonymous

Thank you so much . I'll keep that in mind. Do you have time for another problem you can help me ?

- anonymous

So plug it into your calculator, and plug x=1, You'll not get a solution there, since there is a vertical asympotoe.

- anonymous

Sure.

@zordoloom

- anonymous

Still loooking at it.

- anonymous

Me to . I'm adleasttrying to work it out to see if i get the right answer.

- anonymous

Is that a 6b in the denominator?

- anonymous

That's defiantly a typo. it should be n.

- anonymous

Say what now ?

- anonymous

Assuming it's a typo, the correct answer is the second one.

- anonymous

The b in the denominator is a typo, a mistake. There is no answer with a b in it, therefore no solution exist. But if you replace the "b" with a "n" you get the second choice that is listed.

- anonymous

I got that to well almost. Kinda of similar. Can you please Show me work on how you got that so i can write it down and comapre it mine.

- anonymous

Do you not trust me?

- anonymous

I do haha, but im very aware of my grades and answers so i will ask are you 100% lol sorry

- anonymous

Your a big help & i wanna thank you

- anonymous

100%. but again there is a mistake in the question.

- AravindG

@zordoloom a better idea would hav been guiding her to that solution instead of pointing out which option is right ..that way she could have understood it 100%

- anonymous

You start by factoring the top part and get (x+1)(x+2)

- anonymous

I dont see a typo. Im checking over my answer on my paper just to double check.

- AravindG

@Kayy_Drizzyy did you like my calculator ? :)

- anonymous

And then factor the denominator and get (x+2)(x+4)

- anonymous

Alright @zordoloom Thanks a lot you were a lot of help.

- anonymous

|dw:1359126064965:dw|

- anonymous

Okay i see . I'm writting it down.

- anonymous

|dw:1359126148210:dw|

- anonymous

Are you good with complex fractions ? & thank you i understand that problem now .

- anonymous

Maybe.

- anonymous

More complex than these?

- anonymous

well to be honest im TERRIBLE with this & you helping me with this problem will mean a lot.

- anonymous

I gotta go in 5 minutes.

- anonymous

awww man

- anonymous

So post the question.

- anonymous

- anonymous

I would say its the last option.

- anonymous

You would say ? Lol are you sure? Do we need to review

- anonymous

I'm sure.

- anonymous

It's none of the first 3, that's for sure. So it must be the last one.

- anonymous

Were any of the previous answer wrong?

- anonymous

*answers.

- anonymous

I havent submited it yet. So im not sure. But you can go now. Thank you so much for your help.

- anonymous

Yep.
