Suppose that the functions \( r \) and \( s \) are defined for all real numbers \( x \) as follows.
\( r ( x ) = 3 x + 2 \)
\( s ( x ) = x - 2 \)
Write the expressions for \( ( r + s ) ( x ) \) and \( ( r \cdot s ) ( x ) \) and evaluate \( ( r - s ) ( 1 ) \)
\( ( r + s ) ( x ) = \square \)
\( ( r \cdot s ) ( x ) = \square \)
\( ( r - s ) ( 1 ) = \square\)
