Question

If $y=e^{x}find\frac{dy}{dx}$

• A. $e^x$
• B. $\frac{e}{x}$
• C. $x{e}^{x-1}$
• D. none of these

Answer 1

The correct option is A

$e^x$

$\frac{d{e}^x}{dx}=e^x$
$\frac{dy}{dx}$ for some common functions
$\begin{array}{cccc}y& \frac{dy}{dx}& y& \frac{dy}{dx}\\ x^n& n{x}^{n-1}& secx& secxtanx\\ sinx& cosx& cosecx& -cosecxcotx\\ cosx& -sinx& lnx& \frac{1}{x}\\ tanx& se{c}^{2}x& e^x& e^x\\ cotx& -cose{c}^{2}x& & \end{array}$
