Answer
D: {All real numbers, $x\ne 2$}
R: {All real numbers, $y\ne 1$}
Vertical asymptote at $x=2$
Work Step by Step
There is a vertical asymptote at $x=2$, so that is where we get our restriction on our domain.
There is a horizontal asymptote at $y=1$, so that is where we get our restriction on our range.
