The derivative of the function/ -3*(y)-6*log(y)

Derivative of -3(y)-6log(y)

The solution

You have entered [src]

-3*y - 6*log(y)

$$- 3 y - 6 \log{\left(y \right)}$$

-3*y - 6*log(y)

Detail solution

Differentiate $- 3 y - 6 \log{\left(y \right)}$ term by term:
1. The derivative of a constant times a function is the constant times the derivative of the function.
  1. Apply the power rule: $y$ goes to $1$
  So, the result is: $-3$
2. The derivative of a constant times a function is the constant times the derivative of the function.
  1. The derivative of $\log{\left(y \right)}$ is $\frac{1}{y}$ .
  So, the result is: $- \frac{6}{y}$
The result is: $-3 - \frac{6}{y}$

The answer is:

$-3 - \frac{6}{y}$
