y=
-32=
-32 = -32
Ответ : точка B проходит через график функции y =
<span>2<span>a^3</span>+<span>a^2</span>−1−3<span>a^2</span>+<span>a^3</span>−a=</span><span>3<span>a^3</span>−2<span>a^2</span>−1−a=</span><span><span>3<span>a^3</span>−2<span>a^2</span>−a−1</span></span>
AB=(-4;-6;-8)
CD=(4;0;0)
EF=(4;0;-8)
2)
AB=(-6;7;1) |AB|=sqrt(49+1+36)=sqrt(86)
AB=(-4;-5;-4) |AB|=sqrt(16+16+25)=sqrt(32+25)=sqrt(57)
AB=(-1;2;-2) |AB|=sqrt(1+4+4)=3
