Question

Using the function below: {(-5,2),(1,1),(5,1),(2,6)} f(1) = f(2)=

Answer 1

$\bf \{(-5,2),(1,1),(5,1),(2,6)\}\implies \begin{array}{|cc|ll} \cline{1-2} x&f(x)\\ \cline{1-2} -5&2\\ 1&1\\ 5&1\\ 2&6\\ \cline{1-2} \end{array} \begin{array}{llll} \\[1em] \leftarrow f(1) = 1\\\\ \leftarrow f(2)=6 \end{array}$
