Answer
The domain is all real numbers except $x\ne0$, and $x\ne7$.
Work Step by Step
Restrictions in a domain occur when any value of $x$ results in an zero in the denominator. To find this value, set the expression in the denominator equal to zero, and solve.
$x^{2}-7x=0$
$(x)(x-7)=0$ Factor and solve
$x=0$ and $x=7$
Thus, the domain is all real numbers except $x\ne0$, and $x\ne7$.
