Question #N905
The function f is defined by $f(x) = \frac{x^2 - 4}{x - 2}$. For what value(s) of x is the function f undefined?
A. x = 2
B. x = -2
C. x = 2, -2
D. x = 0, 2
Correct Answer is: A
A function is undefined when the denominator equals 0. The denominator of the given function is x - 2. Setting x - 2 = 0 and solving for x, we get x = 2. Therefore, the function is undefined for x = 2.
