Best ResponseYou've already chosen the best response.1which part u didn't get ? for limit to be continuous, u need to have lim x>0 ... = lim x>0+ ..

Best ResponseYou've already chosen the best response.1because the point of discontinuity can be 0 only... as the function behaves differently (different definition) before and after 0

Best ResponseYou've already chosen the best response.1because of the domain restrictions?

Best ResponseYou've already chosen the best response.1u 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

Best ResponseYou've already chosen the best response.1okay... how does a=b?

Best ResponseYou've already chosen the best response.1because , for continuity , lim x>0 needs to be equal to x>0+ and lim x>0 was 1 so, x> 0+ = a/b = 1
