Determine the following limits, using co or - co when appropriate, or state that they do not exist. (X - 8) a. lim (X -8) (X - 8) X(X + 4) b. lim X- - 4# X(X + 4) c. lim X- - 4 X- - 4 X(X + 4) (X - 8) O A. lim x(X+ 4) (Simplify your answer.) X- - 4 O B. The limit does not exist and is neither co nor - co b. Select the correct choice below and, if necessary, fill in the answer box to complete your choice (X - 8) OA. lim X(X + 4) (Simplify your answer.) X - - O B. The limit does not exist and is neither co nor - co c. Select the correct choice below and, if necessary, fill in the answer box to complete your choice (X - 8) O A. lim (Simplify your answer.) X- - 4 X(X + 4) O B. The limit does not exist and is neither co nor - co
