Answer:

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: #{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]}
