Use the properties of limits to help decide whether the limit exists. If the limit exists, find its value. 3x³ +8x-4 lim x-[infinity]0 4x-2x -8 3 ***. Select the correct choice below and, if necessary, fill in the answer box within your choice. OA. lim 3x³ +8x-4 3 = x→[infinity]0 4x² - 2x³-8 (Simplify your answer.) OB. The limit does not exist and is neither [infinity]o nor - [infinity]o.
