2 Let N be the set of natural numbers. Define a real valued function f : N-> N by f (x) = 2x + 1. Using this definition, complete the table given below.

Text Solution

Verified by Experts

Given function is `f(x)=2x+1`
so,
`f(1)=>2(1)+1=3`
`f(2)=>2(2)+1=5`
`f(3)=>2(3)+1=7`
`f(4)=>2(4)+1=9`
`f(5)=>2(5)+1=11`
`f(6)=>2(6)+1=13`
