Question

For what value of x is the reciprocal function f(x)=1x
undefined?

Answer 1

The function \( f(x) = \frac{1}{x} \) is undefined when the denominator is equal to zero. Therefore, we need to find when \( x = 0 \).

So, the reciprocal function \( f(x) = \frac{1}{x} \) is undefined at:

\[
x = 0
\]
