    which part u didn't get ? for limit to be continuous, u need to have lim x->0- ... = lim x->0+ ..

    because the point of dis-continuity can be 0 only... as the function behaves differently (different definition) before and after 0

    because of the domain restrictions?

    u can say that, but mostly its because of t<=0 ..... t> 0 if it were t<=2..... t>2, then u would have checked at x=2

    okay... how does a=b?

    because , for continuity , lim x->0- needs to be equal to x->0+ and lim x->0- was 1 so, x-> 0+ = a/b = 1
