algorithm - 如何找到函数的增长率？

Question

我有三个函数，我必须根据它们的相对增长率（按递增顺序）对它们进行排序。以下是给出的函数：

f(x)=

f(x)=

f(x)=

我不明白如何找到增长率？

Answer 1

To find the growth rate, you could use a spreadsheet and draw graphs for different values.

Once you've done that, take a graph and look at the shape and place them in order of how they grow. Here's a clue 20 * n^18 is much much bigger than log20(n^18).
