Answer 2

Given:

The table of values of a function f(x).

To find:

The value of f(-1).

Solution:

We know that, if

`f(x)=y`

Then, x is input and y is output.

From the given table it is clear that at x=-1 the corresponding value of y is 0.

It means, the output is 0 if x=-1. So,

`f(-1)=0`

Therefore, the value of f(-1) is 0.
