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 \(f\) \(=\) \(\bigg\{\)iiii, ii, ii\(\bigg\}\)
 
Is \(f\) a function from \(A\) to \(A\)? Give reasons.
