Final answer:
The limit as n approaches infinity of 1 - n²/n simplifies to 1 - n, which approaches negative infinity as n becomes very large.
Step-by-step explanation:
To find the value of the limit lim (n→∞) 1 - n²/n, we can simplify the expression under the limit. The expression simplifies to 1 - n. As n approaches infinity, the term -n will become increasingly negative, meaning the overall value will approach negative infinity. Therefore, the answer is D. -∞.
