All real numbers except $\frac{7}{6}$.
The denominator of a fraction cannot be $0$, hence for the domain of the given function is the set that contains any real number except the one that makes $6z-7$ equal to $0$. To find the domain, solve the equation $6x-7=0$ and exclude it from the domain to obtain: $6x-7=0\\ 6x=7\\ x=\frac{7}{6}$ Thus, the domain is the set of real numbers except $\frac{7}{6}.$
