Chapter 2.3, Problem 34E

(a) Use a graph of

$f(x)=\frac{\sqrt{3+x}-\sqrt{3}}{x}$

to estimate the value of $\underset{x\to 0}{\lim }$f(x) to two decimal places.

(b) Use a table of values of f(x) to estimate the limit to four decimal places.

(c) Use the Limit Laws to find the exact value of the limit.
