The primary reason the function f(x) = 1/x is not continuous at x = 0 is that

A.A) The limit of f(x) as x approaches 0 does not exist.
B.B) The function is not defined at x = 0.
C.C) The function has an infinite discontinuity at x = 0.
D.D) The function has a removable discontinuity at x = 0.

Explanation

Core Concept

The primary reason the function f(x) = 1/x is not continuous at x = 0 is that the limit of f(x) as x approaches 0 does not exist because as x approaches 0, f(x) approaches infinity. The function is not defined at x = 0, which is another reason the function is not continuous. Options C and D do not accurately describe the discontinuity of the function.

A
