#### Explanation:

#"let "f(x)=(3x-2)/(x+1)# The denominator of f(x) cannot be zero as this would make f(x) undefined. Equating the denominator to zero and solving gives the value that x cannot be and if the numerator is non-zero for this value then it is a vertical asymptote.

#"solve "x+1=0rArrx=-1" is the asymptote"#

#"horizontal asymptotes occur as"#

#lim_(xto+-oo),f(x)toc" (a constant)"#

#"divide terms on numerator/denominator by "x#

#f(x)=((3x)/x-2/x)/(x/x+1/x)=(3-2/x)/(1+1/x)#

#"as "xto+-oo,f(x)to(3-0)/(1+0)#

#rArry=3" is the asymptote"#
