MCQ
If $y=a e^x+b e^{-x}+c$, where $a, b, c$ are parameters, then $y^{\prime}$ is equal to
  • $a e^x-b e^{-x}$
  • B
    $a e^x+b e^{-x}$
  • C
    $-\left(a e^x+b e^{-x}\right)$
  • D
    $a e^x-b e^x$

Answer

Correct option: A.
$a e^x-b e^{-x}$
(a) : $y=a e^x+b e^{-x}+c$
Differentiating w.r.t. $x$, we get
$
y^{\prime}=a e^x-b e^{-x}
$
