Answer:

all real numbers expect  1.

Step-by-step explanation: This is a rational function. when we  usually the find the domain of a rational function we would look at the bottom because you don't want the denomonatior to be zero because dividing by zero in math makes the range undefined. so we use the equation and set it up to zero to find the domain. 1-x=0 -x=-1, divide by -1 and we get  1.  So x can be any numbers expect 1. Interval notation: (-∞,1)∪(1,+∞)
