Remember the definitions:

$f$ is right$-$continuous at $c$ means $\underset{x{c}^{}}{lim}f(x)=f(c)$

$f$ is left$-$continuous at $c$ means $\underset{x{c}^{-}}{lim}f(x)=f(c)$

Answer these questions about the function $k(x)$ graphed here, and give the reasons:

a$)$ Is $k(x)$ left$-$continuous at $x=-1?$

b$)$ Is $k(x)$ right$-$continuous at $x=-1?$

c$)$ Is $k(x)$ left$-$continuous at $x=1?$

d$)$ Is $k(x)$ right$-$continuous at $x=1?$

e$)$ Is $k(x)$ continuous at $x=1?$

f$)$ Is $k(x)$ left$-$continuous at $x=3?$

g$)$ Is $k(x)$ right$-$continuous at $x=3?$

h$)$ Is $k(x)$ continuous at $x=0?$

i$)$ Is $k(x)$ continuous at $x=-1?$

j$)$ Is $k(x)$ continuous at $x=3?$
