Chapter 11.7, Problem 1P

Identify the excluded value of each rational function.

$y=\frac{2}{x}$

To determine

To identify : the excluded value of the rational function

Answer to Problem 1P

The excluded value of $x=0$

Explanation of Solution

Given information : $y=\frac{2}{x}$

Calculation :

  $y=\frac{2}{x}$

Since this is a rational function the denominator cannot be $0$

Therefore excluded value of $x=0$

The domain of the function is $x\in \left(-\infty ,0\right)\cup \left(0,\infty \right)$
