2 + \/ 3*x + 2 
$$\sqrt{3 x + 2} + 2$$
2 + sqrt(3*x + 2)
Detail solution
  1. Differentiate term by term:

    1. The derivative of the constant is zero.

    2. Let .

    3. Apply the power rule: goes to

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