Suppose that x^2-6x-3 <= f(x) <= sqrt(9-x^2) on [0,3]. Give upper and lower bounds for lim x->0+ f(x) and lim x->3^- f(x) lim (x^2 - 6x - 3) = -3 as x --> 0+ lim v(9 - x^2) = 3 as x -->0+ -3 = f(x) = 3 lim (x^2 - 6x - 3) = -12 as x --> 3- lim v(9 - x^2) --> 0 as x --> 3- -12 = f(x) = 0 (What is the upper bound and lower bound ? I don't know that.) thanks....please answer these four questions perfectly. Only answer them if ur 100% sure.  10-21-2011 #2 lolkidman Join Date: Jun 2011 Posts: 53 ...
