<u><em>Explanation:</em></u> In any fraction, the <u>denominator cannot be equal to zero</u>, otherwise, the function would be <u>undefined</u>. This means that any value that makes the denominator equal to zero would be an excluded value.
<u>In our fraction, the denominator is:</u> b - 2 <u>We will get the value of b that would make the denominator zero:</u> b - 2 = 0 b = 2
This means that the denominator of the given fraction would be zero at b = 2. This means that <u>2 is an excluded value</u>.
