For the function $y = \log_6(x)$:

1. Domain: Since the logarithmic function is only defined for positive values of $x$, the domain is $(0, \infty)$.
2. Range: The range of a logarithmic function, such as $y = \log_6(x)$, is all real numbers, $(-\infty, \infty)$, because the output of a logarithmic function can be any real number.

Thus, the correct answer is:

a. $(0, \infty), (-\infty, \infty)$

Tip: Remember, for $\log_b(x)$ to be defined, $x$ must be positive.
