$$ \text{Domain: All Real Numbers Except 2.5}$$

Work Step by Step

We see that the given function is in the form $f(x)=\frac{p(x)}{q(x)}$, since the values in the numerator and the denominator are functions. Thus, this is a rational function. Since rational functions do not exist when the denominator is equal to zero, it follows: $$ \text{Domain: All Real Numbers Except 2.5}$$
