[Figure: Mapping diagram of a relation f from set A = {a, b, c} to set B = {1, 2, 3, 4}. Arrows: a to 1, a to 3, b to 2, c to 4. So element a has two arrows (to 1 and to 3).] Which of the following is true on the basis of above diagram?

The function \(f(x) = e^{|x|}\) is (A) continuous everywhere on \(R\) (B) not continuous at \(x = 0\) (C) Differentiable everywhere on \(R\) (D) not differentiable at \(x = 0\) (E) continuous and differentiable on \(R\) Choose the most appropriate answer from the options given be…
