Determine the zeros (if any) of the rational function $f ( x ) = \frac { x ^ { 2 } - 9 } { x - 2 }$.
A) $x = 2$
B) $x = \frac { 3 } { 2 } , x = - \frac { 3 } { 2 }$
C) $x = - 9 , x = 9$
D) $x = - 3 , x = 3$
E) no zeros

Quizplus · Accepted Answer

The zeros of the function are the solutions to $x^2 - 9 = 0$, which factorizes to $(x + 3)(x - 3) = 0$, giving $x = -3$ and $x = 3$.
