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       
--------------
    __________
2*\/ 3*x - 14 
$$\frac{3}{2 \sqrt{3 x - 14}}$$
The second derivative [src]
      -9        
----------------
             3/2
4*(-14 + 3*x)   
$$- \frac{9}{4 \left(3 x - 14\right)^{\frac{3}{2}}}$$
The third derivative [src]
       81       
----------------
             5/2
8*(-14 + 3*x)   
$$\frac{81}{8 \left(3 x - 14\right)^{\frac{5}{2}}}$$
