Question 296

Multiple Choice

State the domain of the rational function.
- f(x) =(x−8) (x+6) x2−4f ( x ) = \frac { ( x - 8 ) ( x + 6 ) } { x ^ { 2 } - 4 }


A) (−∞,∞) ( - \infty , \infty )
B) (−∞,−6) ∪(−6,8) ∪(8,∞) ( - \infty , - 6 ) \cup ( - 6,8 ) \cup ( 8 , \infty )
C) (−∞,−2) ∪(−2,2) ∪(2,∞) ( - \infty , - 2 ) \cup ( - 2,2 ) \cup ( 2 , \infty )
D) (−∞,−8) ∪(−8,6) ∪(6,∞) ( - \infty , - 8 ) \cup ( - 8,6 ) \cup ( 6 , \infty )
