# How do you find the derivative f(x)= 3x+2?

Jan 27, 2016

$f ' \left(x\right) = 3$

#### Explanation:

We can find the derivative using the power rule

Reminder: $f \left(x\right) = {x}^{n}$

$f ' \left(x\right) = n {\left(x\right)}^{n - 1}$

also, $g \left(x\right) = c$ , given $c$ is any constant number, then

$g ' \left(x\right) = 0$

Given : $f \left(x\right) = 3 x + 2$

$f ' \left(x\right) = 1 \left(3\right) {x}^{1 - 1} + 0$

$f ' \left(x\right) = 3 x$
