Question #N505
The function \(f\) is defined by \(f(x) = \frac{x^2 - 4}{x - 2}\). For what value(s) of \(x\) is the function undefined?
A. -2
B. 2
C. -2 and 2
D. The function is defined for all values of x.
Correct Answer is: B
A function is undefined when the denominator of a fraction equals zero. In this case, the denominator, \(x - 2\), equals zero when \(x = 2\). Therefore, the function is undefined when \(x = 2\).
