Find the following limits. You may use any theorem we have proved, such as Arithmetic of Limits. (Please do not use any theorem not discussed in class!) Indicate clearly what results you are using. The right answer without a justifiable reason will be given zero credit. i. limn→∞   3n2 + 1                   ------------                       2n2 + 2n - 1. ii. limn→∞    √5n2 + 2n                      ------------                              n + 2   . iii. limn→∞   -3n3 + 4                      ------------                           3n3 + 2n2 - 1n.
