Evalnate the fo llowing limits 1. lim 4x-5x+1 メ→ -4x? 2. lim I x²+5x -6 X- 4 lim (1x-7)* 3. 2.

Evaluate each of the following limits. +1 1. lim Зх — 5 X 00

Evaluate the following limits algebraically if they exist, showing all your work as done in lecture. If the limit does not exist, answer DNE; if it is infinity, answer ∞, if it is negative infinity, answer -∞. Leave answers in exact form (i.e. if the answer is 1/4, you may answer 1/4 or 0.25, but if the answer is 1/3, you must leave it as 1/3). Arguments that use numerical estimation or a graph will receive 0 credit. It is especially important to show all your work for these questions. x2 3 1 A. lim x 2 X tet B. lim to et + 1 x² + x - 2 C. lim x-1 x² - 1 Remember that if you choose to use L'Hospital's rule, you must check all necessary assumptions and use proper notation. None of these limits require L'Hospital's rule. - 2

eed to rewrite each limit to get a vali 2x 8. lim 2x2 x-1 x+1
