# How do you find the domain and range of f(x)=3x-2?

Oct 2, 2017

Domain $\left\{x \in \mathbb{R}\right\}$

Range $\left\{y \in \mathbb{R}\right\}$

#### Explanation:

This is just the equation of a straight line. The function is continuous so the domain is:

$\left\{x \in \mathbb{R}\right\}$

The minimum value is $- \infty$
The maximum value is $\infty$

So the range is:

$\left\{y \in \mathbb{R}\right\}$
