Which of the following statements about the function f(x) = (x^2 - 4)/(x - 2) is true?

A.D) The function is continuous at x = 2, and the limit of f(x) as x approaches 2 also exists.
B.C) The function is not continuous at x = 2, but the limit of f(x) as x approaches 2 exists.
C.B) The primary reason the limit of f(x) as x approaches 2 exists is that the function is continuous at this point.
D.A) The function is continuous at x = 2, but the limit of f(x) as x approaches 2 does not exist.

Explanation

Core Concept

The function f(x) = (x^2 - 4)/(x - 2) is not continuous at x = 2 because it is undefined at this point, but the limit of f(x) as x approaches 2 exists. Option A is incorrect because the function is not continuous at x = 2. Option B is incorrect because the function is not continuous at x = 2. Option D is incorrect because the function is not continuous at x = 2.

C
