Question #N75
The function $f(x) = \frac{x^2 - 4}{x-2}$ is undefined for what value of $x$?
A. -2
B. 2
C. 4
D. 8
Correct Answer is: B
The function is undefined when the denominator is equal to zero. The denominator, $x-2$, is equal to zero when $x=2$. Therefore, the function is undefined for $x = 2$.
