Let the function f be defined by the equation y = f(x), where x and f(x) are real numbers. Find the domain of the function. (Enter your answer using interval notation) f(x) = x + 1 x − 2

Answer 1

if it is (x+1)(x-2) then it is a polynomial (quadratic) which has domain all reals

(-infinity, infinity)

if it is (x+1)/(x-2) then the domain is all reals EXCEPT x=2

(-infinity,2) U (2,infinity)
