Use the given formal definition to prove the limit statement. lim = DO X- 6 X-6+ The function f(x) approaches infinity as x approaches c from the right, written lim f(x) = co, if, xact for every positive real number B, there exists a corresponding 6 > 0 such that for all x, CB. Complete the introductory statement. Given B > 0, find 8 > 0 such that for all x, 6 B X - 6 Complete the statement. > B if and only if x
