This exercise explores the difference between the limit
Chapter 4, Problem 84E(choose chapter or problem)
This exercise explores the difference between the limit
\(\lim _{x \rightarrow \infty}\left(1+\frac{1}{x^{2}}\right)^{x}\)
and the limit
\(\lim _{x+\infty}\left(1+\frac{1}{x}\right)^{x}=e\)
a. Use l'Hôpital's Rule to show that
\(\lim _{x+\infty}\left(1+\frac{1}{x}\right)^{x}=e\)
b. Graph
\(f(x)=\left(1+\frac{1}{x^{2}}\right)^{x} \text { and } g(x)=\left(1+\frac{1}{x}\right)^{x}\)
together for \(x \geq 0\).How does the behavior of \(f\) compare with that of \(g\)? Estimate the value of \(\lim _{x \rightarrow \infty} f(x)\).
c. Confirm your estimate of \(\lim _{x \rightarrow \infty} f(x)\) by calculating it with l'Hôpital's Rule.

lim over x rightarrow infinity (1 + 1/x^2)^x
lim over x rightarrow infinity (1 + 1/x^2)^x = e
lim over x rightarrow infinity (1 + 1/x^2)^x = e
f(x) = (1 + 1x2)^x and g(x) =(1+1x)^x
x geq 0
