point(s) possible
A. all real numbers the correct choice below, and if necessary, fill in the answer box to complete your choice.
B.
C.
D. all real numbers except

The function is a rational function, which means we need to identify values of that might make the denominator zero. Setting the denominator equal to zero gives us , which simplifies to . Therefore, the function is defined for all real numbers except .

So, the domain of is all real numbers except . Thus, the correct answer is D: all real numbers except .
