Question

goal
you’re on the right track thinking about infinity! but the problem asks for inequality notation, not just infinities.
for domain, you need to write an inequality using x. for range, you need an inequality using y. what variable should each inequality use?
ask the ai coach a question

Explanation:

Step1: Analyze Domain Variable

Domain of a function refers to all possible \( x \)-values the function can take. So, for domain inequality, we use \( x \).

Step2: Analyze Range Variable

Range of a function refers to all possible \( y \)-values the function can take. So, for range inequality, we use \( y \).

Answer:

For domain inequality, use \( x \); for range inequality, use \( y \).
