v

The graph:

from to

Piecewise:

The solution

You have entered [src]
log(x) - 2*x
$$- 2 x + \log{\left(x \right)}$$
log(x) - 2*x
Detail solution
  1. Differentiate term by term:

    1. The derivative of 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:
