Answer 1

Answer:

I don't you can do it yourself

Answer 2

Answer:

A={9,10,11,12,13}

f:A→N is defined as

f(n)= The highest prime factor of n

Prime factor of 9=3

Prime factors of 10=2,5

Prime factors of 11=11

Prime factors of 12=2,3

Prime factors of 13=13

∴f(9)= The highest prime factor of 9=3

f(10)= The highest prime factor of 10=5

f(11)= The highest prime factor of 11=11

f(12)= The highest prime factor of 12=3

f(13)= The highest prime factor of 13=13

Thus range of f is the set of all f(n) where n∈A

is ={3,5,11,13}
