Identify the domain of the following function: f(x) = x+1/x-2

1.	Identify the domain of the following function: f(x) = x+1/x-2
Answer» Answer: The value of f(X) is real for all real values of x except 2, because is x = 2, then the DENOMINATOR is = 0, and the whole fraction tends to infinity, i.e. not defined. So THEREFORE, D = R - {2}, where R is the SET of real numbers, {2} in curly brackets denoted that the set contains only one value, which is 2. Hope you understood.

D = R - {2}, where R is the SET of real numbers, {2} in curly brackets denoted that the set contains only one value, which is 2.
