Answer 1

Given:

The table of values.

To find:

The function for the given table.

Solution:

From the given table it is clear that the y-values are same as the corresponding x-values. It means y is directly proportional to x with 1 as a constant of proportionality.

Mathematically, it can be defined as:

$y=1\times x$

$y=x$

Substitute $y=f(x)$ in the above equation to find the required function.

$f(x)=x$

Therefore, the correct option is A.
