Answer
a. $ 8$
b. $ 8 $
C. $ 8$
d. $g$ continuous at $x=4$
Work Step by Step
From the given figure:
a. $\lim _{x \rightarrow 4^{-}} g(x)= 8$
b. $\lim _{x \rightarrow 4^{+}} g(x)=8 $
C. $g(4)=8$
d. Since $\lim _{x \rightarrow 4^{+}} g(x)= \lim _{x \rightarrow 4^{-}} g(x)= g(4)$ , $g$ is continuous at $x=4$
