Find any numbers for which the rational expression is undefined.
-$\frac { 3 y - 2 } { y ^ { 2 } - 64 }$
A) $y = \frac { 2 } { 3 }$
B)y = 64
C)y = 8, y = -8
D)y = 8

Question

Quizplus · Accepted Answer

A rational expression is undefined when its denominator is zero. The denominator of the given expression is $y^2 - 64$, which factors to $(y - 8)(y + 8)$. Therefore, the expression is undefined for $y = 8$ and $y = -8$.
