The function f in the y=f(x) equation that is behind that graph is how scalable your application is.
这个y=f(x)方程的图像所显示出来的f函数,就是你的应用的伸缩能力。
The first person let me go ahead and check out before him because of (x); other people did the same thing because of f(x). The essence of (x) is unknown.
第一个让我先结账的人是因为(x),而其他人这么做是因为(x),而这个x却是未知的。
We have the integral from minus infinity to plus infinity of F(x)*x*dx, and that's really--you see it's the same thing because an integral is analogous to a summation.
我们用从负无穷到正无穷的积分公式F(x)*x*dx,你看到的,这是相同的事,因为积分是类似的求和过程。
