. Let A = R ˜ {m}and B = R ˜ {n}, where R is a set of real numbers. Let f(x) = (x - n)/(x - m), then f is (where m, n are any integers) A. one-one onto B. many one onto C. one-one into D. many one into

Hello student,
Please find the answer to your question below
Given f(x)=(x-n)/(x-m)
As if x=n it becomes 0
also all the values are not pesent in codomain like 2,3 etc...
So the given function is one-one and into
Hence C is the correct answer
