If |f(x)| is continuous at x=a , then f(x) is

Options

  1. Acontinuous at x=a
  2. Bcontinuous at x=-a
  3. Ccontinuous at x= a
  4. Dnot be continuous at x=a

Correct answer

D. not be continuous at x=a

Step-by-step solution

|f(x)| is continuous at x=a, f(x) is not be continuous at x=a . |f(x)|= array cc f(x), & x a -f(x), & x a array .
