If 3x − 3 ≤ f(x) ≤ x2 − 3x + 6 for x ≥ 0, find lim x→3 f(x).

Answer:     ======use the squeeze theorem.(j. stewart, “calculus”, 7th ed., brook/coles.)if, near a point  ,  there is afunction  thatis "sandwiched" between two functions  and  with  and      then  ======we are looking for      since we have    then we need to verify that  and  are the same to evaluate the limit for f.    and    therefore
