In Exercises $39 - 44 ,$ use the graph to estimate the limits and value of the function, or explain why the limits do not exist.
$$( \mathbf { a } ) \lim _ { t \rightarrow - 4 ^ { - } } g ( t )$$
$$( \mathbf { b } ) \lim _ { t \rightarrow - 4 ^ { + } } g ( t )$$
$$( \mathbf { c } ) \lim _ { t \rightarrow - 4 } g ( t )$$
$$( \mathbf { c } ) g ( - 4 )$$
