$$e^{\left(-2\right) x}$$

E^(x*(-2))

Detail solution

Let $u = \left(-2\right) x$ .
The derivative of $e^{u}$ is itself.
Then, apply the chain rule. Multiply by $\frac{d}{d x} \left(-2\right) x$ :
1. The derivative of a constant times a function is the constant times the derivative of the function.
  1. Apply the power rule: $x$ goes to $1$
  So, the result is: $-2$
The result of the chain rule is:

$- 2 e^{\left(-2\right) x}$
Now simplify:

$- 2 e^{- 2 x}$

The answer is:

$- 2 e^{- 2 x}$
