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) $\text { not a function }$

A relation is a function if each input (x-value) has exactly one output (y-value). In this relation, each x-value is paired with exactly one y-value, so it is a function. The domain (all the x-values) is $\{-4,-3,0,3,5\}$, and the range (all the y-values) is $\{11,4,-5,20\}$.
