Transform

Detail solution

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

The answer is:

$3 x^{2} - 4 x - 1$
