vertical asymptotes are #x=1# and #x=1 1/2#

horizontal asymptote is #y=1 1/2#

no removable discontinuities ("holes")

#f_((x))=(3x^2-1)/(2x^2-5x+3)=(3x^2-1)/((2x-3)(x-1))#

#x_(d_1)=3/2#

#x_(d_2)=1#

#x_u=+-1/sqrt3#

#=>#
#x_(d_1)!=x_(d_2)!=x_u#
#=>#
there're no holes

#=>#
vertical asymptotes are #x=1# and #x=1 1/2#

#lim_(x rarr +-oo)f_((x))=1 1/2#

#=>#
horizontal asymptote is #y=1 1/2#
