Answer 1

omfg are you in the cities right now?

Answer 2

what?

Answer 3

no. i am going into 9th grade

Answer 4

what are u talking about with all this campus stuff

Answer 5

An 8th grader wouldn't be doing this question BTW

Answer 6

i talk math at the university of minnesota. not at school. its called umtymp

Answer 7

Their online program?

Answer 8

no i go there once a week during the school year. this summer they gave us summer hw

Answer 9

can u help me or not

Answer 13

@jim_thompson5910 - can you help muzzammil with this question?

Answer 14

thanks

Answer 15

i wasn't planning on meeting him

Answer 16

I could tell you weren't- I just felt like I should say something. Weird. This is usually a really good site to get help with studies. Some people (like this one and the ones in the math room right now) aren't here for the right reasons.

Answer 17

@jim_thompson5910 is a wonderful helper. Very smart. And explains things.

Answer 18

if you're given a list of choices, I recommend checking each one by plugging in x = 0 and x = 1

you should get y = 1 when you plug in x = 0
and you should get y = 0 when you plug in x = 1

Answer 19

i am not given any choices i just have to find the equation

Answer 20

ok well this looks like a tangent function

Answer 21

but it's flipped over the x axis, so it's like y = -tan(x)

but it's obviously more complicated than that (it's just an example of its basic form)

Answer 22

and you have to make sure this tangent function goes through (0,1) and (1,0)

so keep that in mind

also, the period looks like it's 4 units, so that effects the equation as well

Answer 23

so how would i solve this

Answer 24

@jim_thompson5910

Answer 25

one sec

Answer 26

hmm not finding much in terms of identifying tangent functions

mainly I'm just finding stuff on sine and cosine functions

Answer 27

same here. so u can't help me

Answer 28

I'll keep looking, but not at the moment, no

Answer 29

\[y= \text{Cot}\left[ \frac{\pi }{4}+\frac{\pi }{4} x\right] \]

Answer 30

thank you

Answer 31

@muzzammil.raza

Thank you for the medal.

If it were not for Mathematica 8 Home Edition's function, FindFit which provided a guide to the solution, I would have probably given up.
