Q91 / 170 · Manipal (MET) 2021 · Mathematics

The function and its derivative are same for

  • A
    $\sin x$
  • B
    $\cos x$
  • C
    $\log x$
  • Correct answer
    D
    $e^x$

Solution

Let $y=e^x$ $\frac{d}{d x}(y)=\frac{d}{d x}\left(e^x\right) \Rightarrow \frac{d y}{d x}=e^x$

Hence, the correct answer is option: 'D'.
