equation:
f(x) = 1/x-2
D(-oo, oo)
how do i figure out the range?
and finding the inverse function?
I know I have to switch the "y" and "x".
I end up getting 1/x + 2, which doesn't look correct.
So once I have the D and R for the f(x) equation the D and R for the F^-1 (x) is the opposite right?
Thanks for your help, really appreciate it.

In America the polynomial long division is done by this way:
http://www.purplemath.com/modules/polydiv2.htm
but in my country the format is different:
the polynomia who should be divided appears in the left-hand and the polynomial who is divided appears in the right hand. Also the quotient appear under the this last polynomial.
Does this approach change anything?

For example, I need number pairs, using numerals 1,2,3,4,5,6 and using each numeral twice. Each sequence should have six pairs. I know this likely doesn't make sense, but I'm math-illiterate, so please forgive me! One example would be 1&2, 3&4, 5&6, 1&3, 2&5, 4&6...thanks.
