Question

sea f(x)=7sin(x)-2x³
f'(x)=
alguna alma caritativa​

Answer 1

Respuesta:

f(x) = 7sen(x)-2x^3

f'(x) = d/dx[ 7sen(x)-2X^3]

f'(x) =d/dx[7sen(x)]+d/dx[-2x^3]

f'(x) = 7×d/dx[sen(x)]+[3×(-2)x^(3-1)]

f'(x)= 7×cos(x)+3(-2x)^2

f'(x) = 7×cos(x)+(-6x^2)

f'(x) = 7×cos(x)-6x^2

R// Si f(x) = 7×sen(×)-2x^3 entonces f'(x) = 7×cos(x)-6x^2
