Identify the rational expression given: \(\frac{5}{x}\).
Recall that a rational expression is undefined when its denominator is equal to zero because division by zero is undefined.
Set the denominator equal to zero to find the values of \(x\) that make the expression undefined: \(x = 0\).
Conclude that the rational expression \(\frac{5}{x}\) is undefined when \(x = 0\).
Therefore, any value of \(x\) other than zero will make the expression defined.
