# How do you find the domain of y = 3x - 11?

Dec 30, 2017

$x \in \mathbb{R}$

Valid for all values of $x$

#### Explanation:

Finding the domain of this function is like asking what value sof $x$ is $y$ defined for, or in other words, whats values of $x$ when inputted will output a real value of $y$

We can see that all values of $x$ will yeild a valid value of $y$

We can see this via sketching the function:

graph{3x-11 [-10, 10, -5, 5]}

$\implies x \in \mathbb{R}$
