Vedclass · Answer

(A) Given $A = \{9, 10, 11, 12, 13\}$ and $f(n) = 	ext{highest prime factor of } n$. We calculate $f(n)$ for each $n \in A$: $f(9) = 	ext{highest prime factor of } 3^2 = 3$. $f(10) = 	ext{highest prime factor of } 2 	imes 5 = 5$. $f(11) = 	ext{highest prime factor of } 11 = 11$. $f(12) = 	ext{highest prime factor of } 2^2 	imes 3 = 3$. $f(13) = 	ext{highest prime factor of } 13 = 13$. The range of $f$ is the set of all output values: $\{f(9), f(10), f(11), f(12), f(13)\} = \{3, 5, 11, 3, 13\}$. Removing duplicates,the range is $\{3, 5, 11, 13\}$.

Let $A = \{9, 10, 11, 12, 13\}$ and let $f: A \rightarrow N$ be defined by $f(n) = \text{the highest prime factor of } n$. Find the range of $f$.
