Answer variants:

\(f\) is not a function from \(A\) to \(A\).
The range is not the subset of \(A\).

\(f\) is a function from \(A\) to \(A\).
The images of the elements of \(A\) belong to \(A\).

If \(A\) \(=\) \(\{\)14, 15, 16, 17\(\}\) and \(f\) \(=\) \(\left\{(x, \frac{1}{x}) : x \in A \right\}\), write down the range of \(f\).

The range of \(f\) \(=\) \(\bigg\{\)

\frac{i}{i}

\frac{i}{i}

\frac{i}{i}

\frac{i}{i}

\(\bigg\}\)

Is \(f\) a function from \(A\) to \(A\)? Give reasons.
