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.

Explanation

To complete the table using the function \( f(x) = 2x + 1 \), we will substitute natural numbers \( x \) from 1 to 7 into the function and calculate the corresponding values of \( f(x) \).

### Step-by-step Solution:

1. **Calculate \( f(1) \)**:
\[ f(1) = 2 \times 1 + 1 = 2 + 1 = 3 \]
