...the inverse for the function: y= (x^2 +1) / (2x -5)
I've been stuck on this question for days, i cant even find the inverse of this equation >_<, please help me. and explain how you got ur answer, thank you!! =D

Domain is all possible "x" values in a function.
Range is all the possible "y" values in the same function.
For this equation, the Domain is "all real numbers EXCEPT 5/2" This is because if you replace "x" with 5/2, the denominator will be 0, which cannot happen.
The range will be "all real numbers" because there are no limitations for "y". If you put any "x" value in the equation, you will get an answer, which is your "y". If you use any number except 5/2, you will get a number. Anyway, ANS. is all real numbers.
