Question #N417
The function $f(x)$ is defined as $f(x) = \frac{x^2 - 4}{x - 2}$. What is the value of $f(2)$?
A. 0
B. 2
C. 4
D. The expression is undefined.
Correct Answer is: D
The function $f(x)$ is undefined when $x = 2$ because this would make the denominator of the fraction equal to 0. Dividing by 0 is undefined.
