\lim_{x \rightarrow 5^{+}} \left| x-2 \right| / x-2

just use direct sub.

|5-2|/(5-2)=3/3=1

myininaya (myininaya):
if x-2>0 (x>2) then |x-2|=x-2 so |x-2|/(x-2)=(x-2)/(x-2)=1 for x>2 if x-2<0 (x<2), then |x-2|=-(x-2)=-(x-2) so |x-2|/{x-2}=-(x-2)/(x-2)=-1 for x<2 since we are looking to the right of the 2, then we are looking at values near 2 that are greater than 2 so the limit is 1
