若正数r为有理数,则\lim_{x \rightarrow +\infty}{\frac{1}{x^{r}}}=0. 若正有理数r使得对任意x,y=x^{r}有意义,则\lim_{x \rightarrow -\infty}{\frac{1}{x^{r}}}=0. 四、无穷远处的无穷极限 当x的取值变大时f\left(x\right)的值亦变大,则\lim_{x \rightarrow +\infty}{x}...
Limits at Infinity:Horizontal Asymptotes水平渐近线 通过下面的例子,来探究 有对应的表格: 对应的图像 得出结论: 定理: 当x越来越大的时候, 对应的 f(x) 越接近 L 读法: 对应的例子: 定理2 也就是到 负无穷大 定理3 (horizontal asymptote 水平渐近线) 只要满足一个, 就可以 y = L, 就是 水平渐近线 定...

(C) is discussing the behavior of the function specifically at x=a, and because horizontal asymptotes are concerned with the function's behavior as it approaches either positive or negative infinity, it doesn't matter what is happening at x=a, so again, this might be true but does not ...

Horizontal Asymptotes: The horizontal asymptotes of functions with the form {eq}y=f(x) {/eq} are determined with limits. However, for functions such as absolute value expressions, it is required to go through the definition of absolute value first. ...

How to Calculate Horizontal Asymptotes Horizontal asymptotes are lines with zero slope which will never be touched by the function. These lines are produced when a rational function has specific degree relationships between the polynomial in the numerator and the polynomial in the denominator. The ...
An Asymptote is a straight line that constantly approaches a given curve but does not meet at an infinite distance. Learn how to find the vertical and horizontal asymptotes with examples at BYJU'S.
