Detail solution
  1. Differentiate term by term:

    1. Differentiate term by term:

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

        1. Let .

        2. The derivative of is .

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

          1. Differentiate term by term:

            1. Apply the power rule: goes to

            2. The derivative of the constant is zero.

            The result is:

          The result of the chain rule is:

        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:

    2. The derivative of the constant is zero.

    The result is:

  2. Now simplify:


The answer is:

The graph
The first derivative [src]
        10 
-10 + -----
      x - 2
$$-10 + \frac{10}{x - 2}$$
The second derivative [src]
   -10   
---------
        2
(-2 + x) 
$$- \frac{10}{\left(x - 2\right)^{2}}$$
The third derivative [src]
    20   
---------
        3
(-2 + x) 
$$\frac{20}{\left(x - 2\right)^{3}}$$
