Write the domain of the rational expression in interval notation.
-$\frac { 5 - t } { t ^ { 2 } + 4 }$
A) $( - \infty , 5 ) \cup ( 5 , \infty )$
B) $( - \infty , - 2 ) \cup ( - 2 , \infty )$
C) $( - \infty , - 2 ) \cup ( - 2,2 ) \cup ( 2 , \infty )$
D) $( - \infty , \infty )$

Question

Quizplus · Accepted Answer

The denominator $t^2 + 4$ is never zero because $t^2$ is always non-negative, making $t^2 + 4 > 0$ for all real numbers $t$. Therefore, the domain is all real numbers.
