Question

Exercícios derive:
1) f(x)= x³ + 2x² + x
2) g(x)= x^4 + x^3 - 3x
3) j(x)= x^2020 + x^2018 + x^2016 + 2014
4) f(x)= 2x (x+40)

Answer 1

Ok, usaremos a vulgarmente chamada, regra do tombo.

1) f'(x) = 3x2 + 4x

2) g'(x) = 4x³ + 3x² - 3

$3) \frac{d}{dx} = {2020x}^{2019} + 2018 {x}^{2017} + 2016 {x}^{2015}$

4)f(x) = 2x² + 80x
f'(x) = 4x + 80
