A) Increasing: $( - \infty , 0 )$ and $( 0.67 , \infty )$ ; decreasing: $( 0,0.67 )$
B) Increasing: $( 0,0.67 )$ ; decreasing: $( - \infty , 0 )$ and $( 0.67 , \infty )$
C) Increasing: $( - \infty , - 2 )$ and $( 2 , \infty )$ ; decreasing: $( - 2,2 )$
D) Increasing: $( - \infty , 0 )$ and $( 0.67 , \infty )$ ; constant: $( 0,0.67 )$
