Multiple Choice

Identify the vertices and asymptotes of the hyperbola. $y ^ { 2 } - x ^ { 2 } = 4$

A) vertices: $( 0 , - 2 ) , ( 0,2 )$ asymptotes: $y = - x , y = x$
B) vertices: $( - 4,0 ) , ( 4,0 )$ asymptotes: $y = - x , y = x$
C) vertices: $( - 2,0 ) , ( 2,0 )$ asymptotes: $y = - x , y = x$
D) vertices: $( - 2,2 ) , ( 2,2 )$ asymptotes: $y = - 2 x , y = \frac { x } { 2 }$
E) vertices: $( 0 , - 2 ) , ( 0,2 )$ asymptotes: $y = - 2 x , y = \frac { x } { 2 }$
