To determine the domain of a linear function, we consider the set of all possible input values (typically represented by \( x \)).
The options provided seem to be specifying ranges for \( y \) and \( x \). Here’s the breakdown:
- The options with {y|...} represent ranges for \( y \), which corresponds to the range of the function.
- The options with {x|...} represent ranges for \( x \), which corresponds to the domain of the function.
For a linear function, if we need to identify the domain, we look for the option that specifies a range for \( x \).
The correct response that represents the domain is:
{x|1≤x≤3}
If you have a linear function, it can take values for \( x \) over the specified interval \( [1, 3] \).
