Question #N70
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 the denominator of a fraction equals 0. In this case, the denominator $x - 2$ equals 0 when $x = 2$. Therefore, the function is undefined for $x = 2$.
