Determine the X Values That Cause the Function to Be f(x)=x2(x4)x+6f ( x ) = \frac { x - 2 } { ( x - 4 ) \sqrt { x + 6 } }

Question 181

Multiple Choice

Determine the x values that cause the function to be (a) zero, (b) undefined, (c) positive, and (d) negative.
- f(x) =x2(x4) x+6f ( x ) = \frac { x - 2 } { ( x - 4 ) \sqrt { x + 6 } }


A) (a) {2}\{ 2 \} , (b) {4}(,6) \{ 4 \} \cup ( \infty , - 6 ) , (c) (6,2) (4,) ( - 6,2 ) \cup ( 4 , \infty ) , (d) (2,4) ( 2,4 )
B) (a) {2,4}\{ 2,4 \} , (b) (,6) ( - \infty , - 6 ) , (c) (6,2) (4,) ( - 6,2 ) \cup ( 4 , \infty ) , (d) (2,4) ( 2,4 )
C) (a) {2}\{ 2 \} , (b) {4}(,6) \{ 4 \} \cup (\infty, - 6 ) , (c) (2,4) ( 2,4 ) , (d) (6,2) (4,) ( - 6,2 ) \cup ( 4 , \infty )
D) (a) {2,4}\{ 2,4 \} , (b) (,6) ( \infty , - 6 ) , (c) (2,4) ( 2,4 ) , (d) (6,2) (4,) ( - 6,2 ) \cup ( 4 , \infty )
