Question

calcular a derivada das funções abaixo:
f(x) = x³
f(x) = 5x³
f(x) = 4x³ + 3x² - x + 5

Answer 1

$f(x) = x^3\\\\f'(x) = 3x^2$

::::::::::::::::::::::::::::::::::::::::::::::::::::::::
$f(x) = 5x^3\\\\f'(x)=5*3x^2 = 15x^2$

::::::::::::::::::::::::::::::::::::::::::::::::::::::::
$f(x) = 4x^3+3x^2-x+5\\\\f'(x)=4*3x^2 + 3*2x - 1 + 0\\\\f'(x)=12x^2+6x-1$
