The function f(x) = x^2 sin(1/x) is defined for all x ≠ 0. Which of the following statements about the function is true?

A.A) The function is continuous at x = 0.
B.D) The function approaches 0 as x approaches 0.
C.B) The function has a discontinuity at x = 0.
D.C) The function approaches infinity as x approaches 0.

Explanation

Core Concept

This question tests the student's understanding of continuity and discontinuity. The function has a discontinuity at x = 0 due to the oscillating nature of the sine function and the increasing amplitude of the x^2 term. Option A is incorrect because the function is not continuous at x = 0. Option C is incorrect because the function does not approach infinity; rather, the oscillations become more rapid and extreme. Option D is incorrect because the function does not approach 0; it oscillates.
