You can rewrite the function \{(1,2),\ (-2, 0),\ (3,0),\ (4, 6)\} as table

\begin{array}{cc}x&y=f(x)\\1&2\\-2&0\\3&0\\4&6\end{array}

The domain of the function is the set of all possible values for the variable x. In your case, the domain of the function f(x) is the set \{-2,\ 1,\ 3,\ 4\}.

The range of the function f(x) is the set of all possible values of the variable y. In your case, the range of the function f(x) is the set \{0,\ 2,\ 6\}.

Answer: Domain - \{-2,\ 1,\ 3,\ 4\} (option A), Range - \{0,\ 2,\ 6\} (option D).
