这个图像应该是由4条线段和坐标轴围成的一个实心的正方形
先在第一象限里面做出x+y=1来(取点(1,0)(0,1)
直线x+y=1和坐标轴围成1个等腰直角三角形
然后这个图像沿着Y轴对折做出跟Y轴对称的第二象限的图像.
再做出跟X轴对称的在第三,四象限的图像
最后把4条边里面的都涂黑 我们最后得到的正方形就是函数 |x|+|y|≤1 的图像.
坐标为(1,0)和(-1,0)和(0,1)和(0,-1)组成的图形,注意是四点内的图像。。就是原点周围。。。回答完毕。。
是个转了45度的正方形
过 (-1,0) , (0,1) , (1,0) ,(0,-1)
这四个点是正方形四个顶点,在两个顶点间连线即可
