Let $N$ be the set of natural numbers. Define a function $f: N \rightarrow N$ by $f(x) = 2x + 1$. Using this definition,complete the table given below.
$x$ $1$ $2$ $3$ $4$ $5$ $6$ $7$ $y$ $f(1) = \dots$ $f(2) = \dots$ $f(3) = \dots$ $f(4) = \dots$ $f(5) = \dots$ $f(6) = \dots$ $f(7) = \dots$
| $x$ | $1$ | $2$ | $3$ | $4$ | $5$ | $6$ | $7$ |
| $y$ | $f(1) = \dots$ | $f(2) = \dots$ | $f(3) = \dots$ | $f(4) = \dots$ | $f(5) = \dots$ | $f(6) = \dots$ | $f(7) = \dots$ |
(N/A) To complete the table,we substitute each value of $x$ into the function $f(x) = 2x + 1$:
| $x$ | $1$ | $2$ | $3$ | $4$ | $5$ | $6$ | $7$ |
| $y$ | $f(1) = 3$ | $f(2) = 5$ | $f(3) = 7$ | $f(4) = 9$ | $f(5) = 11$ | $f(6) = 13$ | $f(7) = 15$ |
