Detail solution
  1. Let u=(3)xu = \left(-3\right) x.

  2. The derivative of eue^{u} is itself.

  3. Then, apply the chain rule. Multiply by ddx(3)x\frac{d}{d x} \left(-3\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: xx goes to 11

      So, the result is: 3-3

    The result of the chain rule is:

    3e(3)x- 3 e^{\left(-3\right) x}

  4. Now simplify:

    3e3x- 3 e^{- 3 x}


The answer is:

3e3x- 3 e^{- 3 x}
