Find the domain and range of the inverse of the given function.
-$$f ( x ) = - \frac { 7 } { x }$$
A) Domain: $( - \infty , 0 ) \cup ( 0 , \infty )$; range: all real numbers
B) Domain: all real numbers; range: $( - \infty , 0 ) \cup ( 0 , \infty )$
C) Domain and range: $( - \infty , 0 ) \cup ( 0 , \infty )$
D) Domain and range: all real numbers

The function $f(x) = -\frac{7}{x}$ has a domain and range of $( - \infty , 0 ) \cup ( 0 , \infty )$ because $x$ cannot be zero and the function can take any non-zero real value. The inverse will have the same domain and range.
