The solution

You have entered [src]
log(x - 2)
----------
  log(4)  
$$\frac{\log{\left(x - 2 \right)}}{\log{\left(4 \right)}}$$
log(x - 2)/log(4)
Detail solution
  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. Now simplify:


The answer is:

The graph
The first derivative [src]
      1       
--------------
(x - 2)*log(4)
$$\frac{1}{\left(x - 2\right) \log{\left(4 \right)}}$$
The second derivative [src]
      -1        
----------------
        2       
(-2 + x) *log(4)
$$- \frac{1}{\left(x - 2\right)^{2} \log{\left(4 \right)}}$$
The third derivative [src]
       2        
----------------
        3       
(-2 + x) *log(4)
$$\frac{2}{\left(x - 2\right)^{3} \log{\left(4 \right)}}$$
