Domain $\{11,4,-5,20\}$

question 188

Multiple Choice

Determine whether the relation represents a function. If it is a function, state the domain and range.
- $\{(-4,11) ,(-3,4) ,(0,-5) ,(3,4) ,(5,20) \}$

• A) function
• domain: \( \{11,4,-5,20\} \)
• range: \( \{-4,-3,0,3,5\} \)
• B) function
• domain: \( \{-4,-3,0,3,5\} \)
• range: \( \{11,4,-5,20\} \)
• C) \(\text { not a function }\)
