# How do you find the domain and range of f(x)=1/2(x-2)?

Oct 29, 2017

$x \in \mathbb{R}$
$f \left(x\right) \in \mathbb{R}$

#### Explanation:

We can soon see when graphing the function;
graph{0.5(x-2) [-10, 10, -5, 5]}

Hence as $x \in \mathbb{R}$ then $f \left(x\right)$ is always defined
So $x \in \mathbb{R}$ and $f \left(x\right) \in \mathbb{R}$
