Question #N135
The function \(f\) is defined by \(f(x) = \frac{x^2 - 4}{x - 2}\). For what value of \(x\) is \(f(x)\) undefined?
A. 4
B. 2
C. -2
D. -4
Correct Answer is: B
A function is undefined when the denominator of the fraction is equal to 0. The denominator of \(f(x)\) is \(x - 2\), so \(f(x)\) is undefined when \(x - 2 = 0\). Solving for \(x\), we get \(x = 2\).
