The solution

You have entered [src]
 4    -x
x  + E  
$$x^{4} + e^{- x}$$
x^4 + E^(-x)
Detail solution
  1. Differentiate term by term:

    1. Apply the power rule: goes to

    2. Let .

    3. The derivative of is itself.

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

      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:

      The result of the chain rule is:

    The result is:


The answer is:

The graph
The first derivative [src]
   -x      3
- e   + 4*x 
$$4 x^{3} - e^{- x}$$
The second derivative [src]
    2    -x
12*x  + e  
$$12 x^{2} + e^{- x}$$
The third derivative [src]
   -x       
- e   + 24*x
$$24 x - e^{- x}$$
