How is the graph of (f(x)=\frac{1}{x-2}) related to (y=\frac{1}{x})?

Answer and explanation

Correct answer: (2) units right

The direct answer is A: the graph moves 2 units to the right. Begin with the standard graph \(y=1/x\). Replacing x by \(x-2\) gives \(y=1/(x-2)\), which is a horizontal translation right by 2 units. This is also confirmed by the vertical asymptote: the denominator is zero when \(x-2=0\), so \(x=2\), whereas the original asymptote is x=0. Option A is correct. Option B would correspond to \(1/(x+2)\), a left shift. Option C would require adding 2 outside the fraction, such as \(1/x+2\), which is a vertical shift up. Option D would require subtracting 2 outside, not changing x inside the denominator. Memory cue: inside x, the sign appears reversed: x−2 means right 2 and x+2 means left 2.
