F and G Are Functions Defined by the Following Table

Essay

f and g are functions defined by the following table. $$\begin{array} { | l | c | c | c | c | c | c | c | } \hline x &-3&-2&-1&0&1&2&3 \\\hline f ( x ) &-5&-4&-3&-2&-1&-2&-3 \\\hline g ( x ) & - 4 & 1 &-1&-2&-1&1&4\\\hline\end{array}$$
Determine the following:
(a) (f $+$ g)(2)
(b) (f - g)( - 1)
(c) $( f \cdot g ) ( 0 )$ (d) $( f / g ) ( 3 )$ (e) $( f \circ g ) ( - 2 )$ (f) $( f \circ f ) ( 0 )$ (g) $( g \circ f ) ( - 1 )$ (h) $( g \circ g ) ( - 2 )$
