Which of the following relation is NOT a function

View answer and explanation

Correct option: C

h=\left\{\left(n, \frac{1}{n}\right) \mid n \in \mathrm{I}\right\}

Option C (

h=\{\left(n, \frac{{1}}{{n}}\right) \mid n \in \mathrm{{I}}\}

) is correct because when n=0, 1/n is undefined, thus violating the function definition.
