Detail solution
  1. Apply the product rule:

    ; to find :

    1. Apply the power rule: goes to

    ; to find :

    1. Let .

    2. The derivative of is itself.

    3. Then, apply the chain rule. Multiply by :

      1. Differentiate term by term:

        1. The derivative of a constant times a function is the constant times the derivative of the function.

          1. Apply the power rule: goes to

          So, the result is:

        2. The derivative of the constant is zero.

        The result is:

      The result of the chain rule is:

    The result is:

  2. Now simplify:


The answer is:

The graph
The first derivative [src]
 2*x - 1        2*x - 1
e        + 2*x*e       
$$2 x e^{2 x - 1} + e^{2 x - 1}$$
The second derivative [src]
           -1 + 2*x
4*(1 + x)*e        
$$4 \left(x + 1\right) e^{2 x - 1}$$
The third derivative [src]
             -1 + 2*x
4*(3 + 2*x)*e        
$$4 \cdot \left(2 x + 3\right) e^{2 x - 1}$$
