Question #N846
The function $f(x) = \frac{x^2 - 4}{x - 2}$ is undefined for which value of $x$?
A. -2
B. 0
C. 2
D. 4
Correct Answer is: C
A function is undefined when its denominator equals zero. In this case, the denominator is $x - 2$, which equals zero when $x = 2$. Therefore, the function $f(x)$ is undefined for $x = 2$.
