    well i myself saw such question for the 1st time . so here's my explanation for the next ans. you see x -> 3- i.e less than 3 .but at 3 we have a point and a graph which has values for x>3 but less than 3 we have no value for fx so limit doesn;t exist i think

    @amir.sat is that the limit does not exist the right answer for the second one?

    So the correct answer for this one is if you approach at 3 the answer is -1

    no if u approach 3 from left just left the answer is -1 for right it's -4 but again as the question want the left limit the answer is -1 but remember if the question just said limit at x =3 it doesn't have any limit imean if doesn't mentioned left or right

    ok it said lim f(x) x->3^- the - in power means get the left limit so as u see it has left limit and it's -1
