<reasoning>

Identify the function type

Using the Domain and Range knowledge point
\[
f(x) = -4x + 8
\]

Analyze domain restrictions

Using the Domain and Range knowledge point

  • No division by zero exists.
  • No square roots of negative numbers exist.
  • The polynomial is defined for all real numbers.

\[
x \in (-\infty, \infty)
\]
</reasoning>

<answer>
Find the domain of the function.
\(f(x) = -4x + 8\)

The domain is <blank>\((-\infty, \infty)\)</blank>. (Type your answer in interval notation.)
