You may have several options, but here is a simple solution:  change your
plot range from {x,-5,5} to {x,1,5} and add AxesOrigin->{0,0} in the plot
command.  If you don't include the command AxesOrigin->{0,0}, your plot may
look misleading.  Please also note that at x = 1, you may have a singular
point.

J. Batista
