The solution

You have entered [src]

-7*x + 4

$$4 - 7 x$$

-7*x + 4

Detail solution

Differentiate $4 - 7 x$ 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: $x$ goes to $1$
  So, the result is: $-7$
2. The derivative of the constant $4$ is zero.
The result is: $-7$

The answer is:

$-7$
