Detail solution
  1. Let .

  2. Apply the power rule: goes to

  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:

  4. Now simplify:


The answer is:

The graph
The first derivative [src]
           3
8*(2*x - 1) 
$$8 \left(2 x - 1\right)^{3}$$
The second derivative [src]
             2
48*(-1 + 2*x) 
$$48 \left(2 x - 1\right)^{2}$$
The third derivative [src]
192*(-1 + 2*x)
$$192 \cdot \left(2 x - 1\right)$$
