The problem asks for the domain of the function based on a table provided.

The domain of a function consists of all the possible input values (X). In this case, the values listed under the "X" column are:

$X = \{ 1, 4, 8, 14 \}$

So, the domain of the function is $\{1, 4, 8, 14\}$.

The correct answer is: 1, 4, 8, 14 (option 1).

Would you like more details, or do you have any questions?

Here are 5 related questions for further exploration:

1. What is the range of the function from the table?
2. How do you find the domain of a function from a graph?
3. What does it mean for a function to be continuous on its domain?
4. How can you determine if a function is one-to-one from its domain and range?
5. What is the difference between the domain and the codomain of a function?

Tip: The domain of a function represents all valid input values, while the range consists of the corresponding output values.
