截距。
y 轴截距来自 f(0);x 轴截距来自求解 f(x) 等于 0。
输入或拍摄函数。AskSia 识别截距、渐近线、对称性、临界点、拐点、端点行为,并详细描述图形。
要绘制函数图,请识别其关键特征:y 轴截距(x 等于 0 时的值);x 轴截距(函数的零点);垂直渐近线(函数未定义处);水平或斜渐近线(端点行为);对称性(偶函数、奇函数、都不是);临界点(导数为零或未定义处);拐点(二阶导数为零或符号改变处)。结合这些来绘制草图。AskSia 会通过计算过程来识别每个特征。
每一步都透明,每个答案都经过自我检查。
y 轴截距来自 f(0);x 轴截距来自求解 f(x) 等于 0。
垂直渐近线来自奇点;水平渐近线来自无穷远处的极限。
来自一阶和二阶导数。
当 x 趋近于正负无穷时的行为。
