Bom, tem uma regrinha p se calcular derivada desse tipo!
Seja x^a, onde a é um número qualquer....a derivada de x^a será:
a . x^(a-1) (onde ^ é a simbologia p mostrar que está elevado)
Exemplo:
f(x)=x^2
f(x)`=2x
f(x)=4x^5
f(x)`=4.5.x^(5-1)=20x^4 (onde f(x)` representa a derivada)
Agora p resolver a derivada da sua função:
f(x)=3x^2+3x
f(x)`=2.3.x^(2-1) + 1.3.x^(1-1)=6x + 3

Regra do tombo
f ( x )= 3x^2 + 3x
f ' ( x ) = 2.3x^1 + 1.3.x^0
f ' ( x ) = 6 x + 3
