Number 63 Draw the graph of f At what points c in domain of f does lim x—-> f(x) existAt what point c does only the left hand and right hand limit exist

EXPLANATION
Graphing the function:
a) As we can see on the graph, For c<0, c>2 and c=1, the Limit doesn't exist.
b) At none point just the left and right hand limit exist.
