Hold a regular meting of the party secretary every fortnightly, arrange the work of the regiment, fedback the student information. Focus on training junior high school, junior high school secretary of the regiment branch to enable them to raise A firm political conviction, diligent and diligent learning spirit and practical and innovative work style.26.1.2 反比例函数的图像和性质（1）学习目标： 1.进一步作函数图象的主要步骤，会作反比例函数的图象。2.体会函数三种表示方法的相互转换，对函数进行认识上的整合。3.探究并掌握反比例函数的性质,体会分类讨论思想、数形结合思想的运用。重点：掌握反比例函数的作图。难点：反比例函数三种表示方法的相互转换。学习过程:一、预习新知 完成以下问题 .⑴ 画函数的图象：⑵ 求上述函数与轴、轴的交点坐标。思考 1.什么叫做反比例函数？假如两个变量、之间的关系可以表示成（为常数且）的形式那么是的反比例函数。反比例函数的自变量不能为零。 2.试猜想反比例函数的图象是什么样的？自己尝试作反比例函数，，的图象。3. 作函数图象的一般步骤是 ， ， 。二、课堂展示 【例】画出反比例函数与的图象。解：① 列表x② 描点以表中相对应的值作为点的坐标，在直角坐标系内描出相应的点Strengthen the team connection, strengthen the knowledge education among the students (especially the first grade students), and promote the formation of good school spirit with the influence of the league members. All League branches should start with recommending outstanding students as the development objects of the League, take amateur league schools as the basis, conscientiously do a good job in the work of pre-league education, league membership education, League members' vanguard exemplary consciousness education, excellent league members' education, etc. Under the premise...
