(1 point) Let 18+x, x f ( 20 ) = 19 - -3. Find the indicated one-sided limits of f, and determine the continui of f at the indicated point. You should also sketch a graph of y = f(a), including hollow and solid circles in the appropriate places. NOTE: Type DNE if a limit does not exist. lim f(x) = x->-3 lim f(x) = x- -3+ lim f(ac ) = x--3 f ( - 3) = Is f continuous at -3? (YES/NO)
