Question #N650
The function \(f(x)\) is defined by \(f(x) = \frac{x^2-4}{x-2}\). For what value(s) of \(x\) is the function undefined?
A. x = 2
B. x = 4
C. x = -2
D. x = 2 and x = -2
Correct Answer is: A
A function is undefined when the denominator of a fraction equals 0. In the given function, the denominator is x-2, which equals 0 when x = 2. Therefore, the function is undefined when x = 2.
