Based on the graph of f(x) = 1/x, which of the following is a correct statement about the function?

A.The function is continuous for all x ≠ 0
B.The function has a removable discontinuity at x = 0
C.The function has an infinite discontinuity at x = 0
D.The function has a jump discontinuity at x = 0

Explanation

Core Concept

The graph of f(x) = 1/x shows that the function approaches ∞ as x approaches 0 from the right and approaches negative ∞ as x approaches 0 from the left. This indicates that the function has an infinite discontinuity at x = 0. Options A and B are incorrect since the function is not continuous at x = 0. Option D is incorrect since the function does not have a jump discontinuity at x = 0.

Correct Answer

CThe function has an infinite discontinuity at x = 0
