Question

What is the derivative of the sum of two functions?

Answer 1

The derivative of the sum of two functions is the sum of their derivatives.

The derivative of a sum of two functions $=$ Derivative of the first function $+$ Derivative of the second function

If $f\left(x\right)$ and $g\left(x\right)$ are two functions, then

$\left(f+g\right)\text{'}\left(x\right)=f\text{'}\left(x\right)+g\text{'}\left(x\right)$
