求数学高手帮忙解7道数学题（calculus）,急用,.
1-7 Find extreme values,inflection points
1.f(x)=x^2-10x+7
2.f(x)=-4x^3+3x^2+18x
3.g(x)=1/3x^3+1/2x^2-2x-2
4.f(z)=(4-z)^4
5.h(x)=x^4-1/3x^2-3/2x^2
6.f(x)=x(1-x)^3
7.h(x)=x√x+3

Answer 1

主要是求导数1 求导后f(x)=2x-10 令f(x)=0 解得 inflection points x=5 extreme values =-182 求导后f(x)=-12x^2+6x+18 令f(x)=0 解得 inflection points x=-1 and 1.5 extreme values =-19 and 20.25那个是抄袭我...
