单泉彬4541知道函数解析式怎么画出函数图象.比如,y=2x - 1、这个根据什么能画出图象..学姐学哥们帮帮我.谢谢了. -
沈俊珍19333679033 ______ 首先了解每个函数的基本图像 y=ax+b 的图像是一条直线 所以只需要2个坐标点 即可确定它的图像 x=o,y=-1 : y=0,x=1/2 在坐标轴上找到(0,1)、(1/2,0) 两点 然后过两点作条直线 即可确定函数的图像
单泉彬4541函数图象
沈俊珍19333679033 ______ 对函数图象首先心中有数,最常用的是描点法画图,即列表再描点.找出函数与自变量之间的关系,列表时,自变量在上,函数值在下,点越多,则图象越精确,你的情况是点少,建议多列出几个点,就可以克服你的问题.快捷准确地画出函数图像是学习函数的基本功.除要掌握描点法画图的步骤外,还需掌握快速画各种函数草图的方法.如两点确定一次函数的图像――直线;对称法画反比例函数的图像;三点定位法或五点定位法画二次函数的图像.另外,在画函数图像时,还要注意函数自变量取值范围对图像的影响,有时画出来的图像,只是整个函数图像的一部分.另外还可以利用模型.
