Quotient of two functions

Suppose that the functions f and g are defined as follows.   f(x)=x-2    g(x)=x-2/x-8   Find f/g. Then, give its domain using an interval or union of intervals. Simplify your answers.

if the function goes out of its domain while calculating the limit of that function, can we say that the limit does not exist?

example: Calculate the limit of a function, while x approaches -1 f(x)=x+arccos(x/1-x^2)-1/(x^2)*e^(1/2*x^2) //the function arccosX (X is a real number) is defined for X∈[-1,1], but in this... more
