A) Domain: all point $( x , y )$ such that $y \neq 0$ Range: $( - \infty , 0 )$
B) Domain: all point $( x , y )$ such that $y \neq 0$ Range: $( 0 , \infty )$
C) Domain: all point $( x , y )$ such that $y \neq 0,1$ Range: $( 0 , \infty )$
D) Domain: all point $( x , y )$ such that $y \neq 0,1$ Range: $( - \infty , \infty )$
E) Domain: all point $( x , y )$ such that $y \neq 0$ Range: $( - \infty , \infty )$
