Answer
(a) $ 1.5$
(b) $ 1.5$
(c) $ 1.5$
(d) $ 2$
(e) No
Work Step by Step
From the given figure, we get
(a) $\lim _{t \rightarrow 1^{-}} m(t)=1.5$
(b) $\lim _{t \rightarrow 1^{+}} m(t)=1.5$
(c) $\lim _{t \rightarrow 1 } m(t)=1.5$
(d)$ m(1)= 2$
(e) $m(t) $ is not continuous at $t=1$ , because $$\lim _{t \rightarrow 1^{-}} m ( t )=\lim _{t \rightarrow 1^{+}} m ( t )=\lim _{t \rightarrow 1 } m ( t ) \neq m(1)$$
