The graph of a function \( g \) is shown.
(1)
Use it to state the values (is they exigt) of the following:
(a) \( \lim _{x \rightarrow 2^{-}} g(x) \)
(b) \( \lim _{x \rightarrow 2^{*}} g(x) \)
(c) \( \lim _{x \rightarrow 2} g(x) \)
(d) \( \lim _{x \rightarrow 5^{-}} g(x) \)
(e) \( \lim _{x \rightarrow 5^{+}} g(x) \)
(f) \( \lim _{x \rightarrow 5} 9(x) \)
Solution
Looking at the graph we see that the values of \( g(x) \) approach \( \square \) as \( x \) approaches 2 from the left, but they approach \( \square \) as \( x \) approaches 2 from the right. Therefore \( (a) \lim _{x \rightarrow 2^{-}} g(x)= \) \( \square \) and (b) \( \lim _{x \rightarrow 2^{+}} g(x)= \) \( \square \)
Since the left and right limits are different, we conclude that (c) the limit as \( x \) approaches 2 of \( g(x) \) does not exist.
The graph also shows that (d) \( \lim _{x \rightarrow 5^{-}} g(x)= \) \( \square \) and
(e) \( \lim _{x \rightarrow 5^{+}} g(x)= \) \( \square \)
This time, the left and right limits are the same and so, by this theorem, we have (f) \( \lim _{x \rightarrow 5} g(x)= \) \( \square \)
Despite this tact, notice that \( g(5)+2 \).
