Which of the following statement(s) is/are true?

निम्नलिखित में से कौनसा/कौनसे कथन सही है/हैं?

• A. The function f(x) = |x| + |x + 1| is continuous ∀ x ∈ R
  
  फलन f(x) = |x| + |x + 1| सतत है ∀ x ∈ R
• B. The function f(x) = |x| + |x + 1| is differentiable ∀ x ∈ R
  
  फलन f(x) = |x| + |x + 1| अवकलनीय है ∀ x ∈ R
• C. The function f(x) = |x| + |x + 1| is discontinuous at x = 0, –1
  
  x = 0, –1 पर फलन f(x) = |x| + |x + 1| असतत है
• D. The function f(x) = |x| + |x + 1| is non-differentiable at x = 0, –1
  
  x = 0, –1 पर फलन f(x) = |x| + |x + 1| अन-अवकलनीय है

Answer 1

Answer: (A), (D)

The function f(x) = |x| + |x + 1| is non-differentiable at x = 0, –1


x = 0, –1 पर फलन f(x) = |x| + |x + 1| अन-अवकलनीय है
