# What are the excluded values of y=2/(x-5)?

Jan 29, 2018

$x = 5$

#### Explanation:

The excluded values are values that make the equation undefined.

Since this function is a fraction, we have a special rule here. In fractions, we cannot make the denominator equal to $0$, otherwise it makes the fraction undefined.

$\therefore x - 5 \ne 0$

$x \ne 5$

So, the excluded value here is that $x = 5$.
