n.渐近线

The function approaches zero as x tends to infinity.
这个函数随着x趋向无穷大而接近于零。
The line is asymptotic to the curve as they approach infinity.
随着它们趋向无穷大，这条线与曲线是同渐近的。
In this graph, the x-axis represents time and the y-axis represents distance.
在这个图中，x轴代表时间，y轴代表距离。
The asymptote of the hyperbola is the line that the hyperbola approaches but never touches.
双曲线的渐近线是双曲线接近但永不接触的直线。
The limit of the function as x approaches infinity is zero.
当x趋向无穷大时，该函数的极限为零。
The curve has two asymptotes, one vertical and one horizontal.
这条曲线有两个渐近线，一个是垂直的，另一个是水平的。
The asymptote can be found by dividing the numerator and denominator of the fraction by the highest power of x.
渐近线可以通过将分数的分子和分母除以x的最高次幂来找到。
The line y = mx + b is an asymptote of the hyperbola if it intersects the hyperbola at only one point.
如果直线y=mx+b与双曲线只有一个交点，则它是双曲线的渐近线。
The function's behavior as x approaches negative infinity can be analyzed by looking at its asymptote.
分析当x趋向负无穷大时函数的行为可以通过观察其渐近线来进行。
The graph shows an exponential function with a horizontal asymptote at y=0.
图表显示了一个以y=0的水平渐近线为特征的指数函数。
