# What is the range of the function f(x) = 5 - 8x ?

Aug 9, 2017

See a solution process below:

#### Explanation:

First, because there are no restrictions on the value $x$ can be, then the domain of the function is the set of Real numbers: $\left\{\mathbb{R}\right\}$

The function is a linear transformation of $x$ and therefore the domain is also the set of Real numbers: $\left\{\mathbb{R}\right\}$

Here's a graph of the function for you to see that domain is $\mathbb{R}$.
