Find the domain of the expression.
-$$\frac { y } { y ^ { 2 } - 64 }$$
A) $\{ y \mid y \neq 8$ and $y \neq - 8 \}$
B) $\{ \mathrm { y } \mid \mathrm { y } \neq 4096$ and $\mathrm { y } z - 4096 \}$
C) $\{ y \mid y \neq 0 \}$
D) $\{ y \mid y \neq 64$ and $y \neq - 64 \}$

The denominator $y^2 - 64$ factors to $(y - 8)(y + 8)$, so the expression is undefined when $y = 8$ or $y = -8$. Therefore, the domain excludes these values.
