Sketch the graph of an example of a function f that satisfies all the of the given conditions.

lim (x->0^+) f(x) = infinity

lim (x->0^-) f(x) = negative infinity

lim (x->infinity) f(x) = 1

lim (x->negative infinity) f(x) = 1
If you can help me with this

This will def need to be done on paint or some graphing thing and uploaded and linked to me!

If you have AIM or MSN, please leave it or ask me to e-mail you for it if you do not wish to post it.

Or just post it here! thanks!
I will give tip (via paypal if you have) if you help me with this

How would you solve that problem? Would you add the exponents together then solve? Or determine the value of the i first?

Solve problems. Show work please.

1.) 2/w=x/5; solve for w

2.) 5d-2g=9; solve for g

3.) y=mx+b; solve for x

ok i asked a question yesterday about percentages and i got
this is the problem i asked:
''in year 1996 the net income for such and such a family was $43,000 and now in 2007, it has risen to $60,000 (i just made up that statistic)
by how much percent did it raise? questions like those! how do i calculate to figure out that answer? what are the steps? please!!! i'm eager to know!!!!''
so i got the answer which was
''60000 MINUS 43000 = 17000 DIVIDED BY 43000 =.395348 OR 39.5348 INCREASE TO CHECK MULTIPLY 1.395348 TIMES 43000= 59999.964 OR NEARLY 60000 SO WAGES HAVE RISEN BY 39.5348. THE ACTUAL INCREASE IS 39.5348837''

the only problem is about the answer is that when they divided
17000 BY 43000 , they got 395348 !!! but when i did it on pen and paper, i got http://www.webmath.com/cgi-bin/dividewrap.cgi?divisor=43000÷nd=17000&back=divide.html

I'm taking a test on problems such as these and we are not allowed to use calculators! so how can i get that same

Radiactive Decay Half Life (T1/2)

In a collection of a great many identical radioactive isostopes, the half- life (T1/2) of the sample is the time it takes for half of the samples to decay.

Question: If the half life of a certain isotope is 4 years, what fraction of a sample of that isotope will remain after 12 years.

I am solving an electromagnetics equation for Chebysheve transformers. My equation I need to solve is:
sec(theta)m = cosh [1/3 cos h ^-1 (1.73 E -01)]
I am not familiar with the sinh, cosh, tanh, etc functions and am unsure how to evaluate the right side of the equation on my scientific calculator. What is the cosh function, and how would I evaluate it on my scientific calculator (TI-83)?
Thank you.

If math is an exact science then i think that if you call the number 33 "thirty three" and the number 21 "twenty one" .... then why not call 16 "onety six"? Shouldn't logic dictate that it should be uniform like that?
