Determine the zeros (if any) of the rational function $g ( x ) = 5 + \frac { 2 } { x ^ { 2 } + 5 }$.
A) $x = - \sqrt { 5 } , x = \sqrt { 5 }$
B) $x = - 2$
C) $x = - \frac { 2 } { 5 } , x = \frac { 2 } { 5 }$
D) $x = - 5 , x = 5$
E) no zeros

Question

Quizplus · Accepted Answer

A rational function can only have zeros where the numerator equals zero. However, the numerator of this function is a constant (5 + 2 = 7), so it can never equal zero. Therefore, there are no zeros for this function.
