常乳宽3608函数(x+y - 1) - xy=0的图像
邰言贷18992508708 ______ x-1+y-xy=0 (x-1)-y(x-1)=0 (x-1)(1-y)=0. 很明显图像是x=1或y=1的两条相交直线.
常乳宽3608y=1/x - 2 +x+1(x>2)的图像最低点坐标 -
邰言贷18992508708 ______ y=1/(x-2)+x+1=(x-2)+1/(x-2)+3>=2+3=5,当且仅当x=3时等号成立.所以,y=1/x-2 +x+1(x>2)的图像最低点坐标是(3,5).
常乳宽3608z^2=x^2+y^2的图像? -
邰言贷18992508708 ______ 圆锥面
常乳宽3608x^2+xy+y^2=0 的图象是什么样的? -
邰言贷18992508708 ______[答案] 图象就只有原点 ∵x^2+xy+y^2=0 ∴(x+1/2*y)^2+3/4*y^2=0 在实数范围内只有一x=0,y=0
常乳宽3608将函数y=x方+x的图像向右平移a(a>0)个单位,得到函数y+x方 - 3x+2的图像.则a的值为?求解释! -
邰言贷18992508708 ______ 将函数y=x^2+x的图像向右平移a(a>0)个单位,得到函数y=x^2-3x+2的图像 y=x^2-3x+2=[x-(3/2)]^2+2-(9/4) 对称轴:x=3/2 原函数:y=x^2+x=[x+(1/2)]^2-(1/4) 对称轴:x=-1/2 a=(3/2)-[-(1/2)]=4/2=2 将函数y=x方+x的图像向右平移a(a>0)个单位,,就是将它的对称轴向右移动a个单位,原来y=x^2+x的对称轴是x=-1/2,现在变成了x=3/2,所以移动单位是a=(3/2)-(-1/2)=2
常乳宽3608x+xy+y=0的图像 -
邰言贷18992508708 ______[答案] y=-x/(x+1) 即是把函数y=1/x的图像向右平移一个单位,再向上平移一个单位可得
常乳宽3608y=︱x+1︱+︱x - 2︱的图像怎么画 -
邰言贷18992508708 ______ 你要去掉绝对值,才能画 当x+1>0,且X-2>0, y=X+1+X-2=2x-1 当x+10,y=-x-1+x-2=-3 此曲线不存在 当X+10,X-2
常乳宽3608x+y+z=0是什么图形 -
邰言贷18992508708 ______[答案] 一个平面. 它的法向量是(1,1,1),用点法式方程表示就是1*(x-0)+1*(y-0)+1*(z-0)=0,所以它是一个通过原点的平面
常乳宽3608y=|x+1|+|2 - x|的图像怎么画 -
邰言贷18992508708 ______ 就是当-1<x<2时, 画y=3.当x>2时,画y=2x-1,当 x<-1时,画 y=-2x+1 我这是对的
常乳宽3608(x+y - 1) - xy=0怎么解.图像是怎样的图象是什么 -
邰言贷18992508708 ______[答案] (x+y-1)-xy=0 -1+x+y-xy=0 -(1-x)+y-xy=0 -(1-x)+y(1-x)=0 (1-x)(y-1)=0 x=1或y=1 图像是相互垂直的两条直线.
