 3      
x  + 4*x

x^{3} + 4 x

x^3 + 4*x

Detail solution

Differentiate $x^{3} + 4 x$ term by term:
1. Apply the power rule: $x^{3}$ goes to $3 x^{2}$
2. The derivative of a constant times a function is the constant times the derivative of the function.
  1. Apply the power rule: $x$ goes to $1$
  So, the result is: $4$
The result is: $3 x^{2} + 4$

The answer is:

3 x^{2} + 4
