Find the limit. (If the limit is infinite, enter 'co' or -co', as appropriate. If the limit does not otherwise exist, enter DNE.) Vt + +2 lim t - 00 8t - +2Guess the value of the limit lim X -00 5 * by evaluating the function f(x) = X for x = 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 20, 50, and 100. Use a graph of f to support your guess. 5 *Two different suppliers are competing to supply a particular part for a new Boeing airliner.
