what is the domain

Answer 1

The domain of a function is the set of all possible input values (x-values) for which the function is defined. Based on the values you've provided for \( x \):

- \( x = -8, -4, -6, 2, 9, 16, 20 \)

The domain includes these specific values of \( x \). Therefore, we can represent the domain as:

\[
\text{Domain} = \{-8, -6, -4, 2, 9, 16, 20\}
\]

If you're looking for a more formal notation, it could also be described as:

**Domain (in set notation)**:
\[
D = \{x \in \mathbb{R} \mid x = -8, -6, -4, 2, 9, 16, 20\}
\]

If the function \( f(x) \) is defined for these specific values of \( x \), then the domain consists of these points.
