# How do you find the domain and range of f(x)= log(x-2)?

Jan 6, 2018

The domain of a function includes all possible $x$ values of a function, and the range includes all possible $y$ values of a function.
Domain: $\left(2 , \infty\right) \left\{x | x > 2\right\}$ since $\log$ is undefined for $0$ or negative values
Range: $\left(- \infty , \infty\right) \left\{y | y \in \mathbb{R}\right\}$
