f(x)=(x-1)e^x-1,则f''(x)=x-1为e的指数f(x)=(x-1)e^x-1,则f''(x)=x-1为e的指数f(x)=(x-1)e^x-1,则f''(x)=x-1为e的指数f(x)=(x

f(x)=(x-1)e^x-1,则f'(x)=x-1为e的指数
f(x)=(x-1)e^x-1,则f'(x)=
x-1为e的指数

f(x)=(x-1)e^x-1,则f'(x)=x-1为e的指数
f(x)=(x-1)e^(x-1)
f'(x)=e^(x-1)+(x-1)e^(x-1)
=xe^(x-1)

f'(x)=(x-1)'*e^(x-1)+(x-1)*[e^(x-1)]'
=e^(x-1)+(x-1)e^(x-1)
=xe^(x-1)


f'(x)=[(x-1)e^(x-1)]'
=(x-1)'e^(x-1)+(x-1)[e^(x-1)]'
=e^(x-1)+(x-1)e^(x-1)(x-1)'
=e^(x-1)+(x-1)e^(x-1)
=xe^(x-1)
