I have two problems that I need help with. In both problems it says to use numerical and graphical evidence to conjecture whether or not the limit at x=a exists. If not, describe what is happening as x=a graphically.
1. the lim as x approches 2 of (x-2)/the absolute value of
2. the lim as x approches 1 of (x^2+1)/(x-1)
