1) lim x->3 f(x) = 0.0001 ; Limit does not exist as left side limit not equals to right side limit
2) lim x ->3+ f(x) = 1 ; Right side limit exists
3) f(2) * f(2) = 3*3 = 9 ; Asking for the value of function and not about limit of the function.
4) lim x->2- f(x) = 3 ; left side limit = value of the function
5) lim x->2 f(x) = 3 ; left side limit = right side limit = value of the function; all three exists and are defined
