Question

Which of the following is NOT a stated notation for the second derivative of \[f(x)\]?

विकल्प

• \[f'(x)\]

• \[f''(x)\]

• \[D^2y\]

• \[y''\]

Answer 1

The notation \[f'(x)\] denotes the first derivative, not the second derivative. Stated second-derivative notations include \[f''(x)\], \[y''\], \[y_{2}\], and \[D^2y\].
