+23254 The domain consists of all possible x-values.
In the function: f(x) = x² + 1, every number can be used for x; therefore the domain of x consists of all real numbers.
In the function: g(x) = 1/x, every number can be used for x except for zero, because division by zero is undefined; therefore the domain of x consists of all real numbers except zero.
