Carlos Arturo · Accepted Answer

Final Answer : E, Explanation :  At x=-13, we get a division by 0 in the denominator of the rational function. Therefore, the function is undefined at x=-13. The correct answer choice is E.

Evaluate the rational function $\frac { 8 x } { x + 13 }$ at x=-13 and simplify. If this is not possible, state the reason.

A) 0
B) -13
C) 4
D) -104
E) undefined ${ (division by } 0 \text { ) }$
