Question #N616
If the function $f(x) = \frac{x^2 - 4}{x - 2}$ is defined, what is the value of $f(2)$?
A. 0
B. 2
C. 4
D. The function is not defined at $x = 2$.
Correct Answer is: D
The function is undefined at x = 2 because the denominator becomes 0 when x = 2, making the expression undefined. The function is not defined at a value where the denominator would equal zero.
