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。
Start Emacs and open a file ([Ctrl]-x[Ctrl]-f) called test.html.
启动 Emacs,然后打开([Ctrl]-x[Ctrl]-f)test.html 文件。
For example, F x y z if I have an equation that looks like this, f of x, y, z.
打个比方,我有个这样的方程。
The power of linearity is F=k1+k2 if I come across f of x, y, z equals k1 plus k2, if it is a linear equation, I don't have to go and solve it all over again.
线性的威力是,一个方程,如果它是个线性方程,那么我就不用再去解他了。
This equation is telling you if you compress it, namely if x is negative, F will be then positive, because it's pushing you outwards.
这个方程告诉我们,如果压缩弹簧,即令 x 为负,F 就为正,因为推力的方向向外
