See a solution process below:

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

The function is a linear transformation of $x$ and therefore the domain is also the set of Real numbers: ${RR}$

Here's a graph of the function for you to see that domain is $RR$ .

graph{5-8x [-10, 10, -5, 5]}

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