Detail solution
  1. Let .

  2. The derivative of is .

  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 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:

      The result is:

    The result of the chain rule is:

  4. Now simplify:


The answer is:

The graph
The first derivative [src]
 7 + 6*x  
----------
   2      
3*x  + 7*x
$$\frac{6 x + 7}{3 x^{2} + 7 x}$$
The second derivative [src]
              2
     (7 + 6*x) 
6 - -----------
    x*(7 + 3*x)
---------------
  x*(7 + 3*x)  
$$\frac{6 - \frac{\left(6 x + 7\right)^{2}}{x \left(3 x + 7\right)}}{x \left(3 x + 7\right)}$$
The third derivative [src]

        x *(7 + 3*x)          
$$\frac{2 \left(-9 + \frac{\left(6 x + 7\right)^{2}}{x \left(3 x + 7\right)}\right) \left(6 x + 7\right)}{x^{2} \left(3 x + 7\right)^{2}}$$
