What is the excluded value? a/b-2 a.0 b.2 3.-2 4.none of the above

The excluded value is 2

Explanation:
In any fraction, the denominator cannot be equal to zero, otherwise, the function would be undefined.
This means that any value that makes the denominator equal to zero would be an excluded value.

In our fraction, the denominator is:
b - 2
We will get the value of b that would make the denominator zero:
b - 2 = 0
b = 2

This means that the denominator of the given fraction would be zero at b = 2. This means that 2 is an excluded value.

Hope this helps :)
