1、Functional Characteristics of Solution for the Equation f(x+y)=f(x)·f(y);
2、the result of a mathematical integration; F(x) is the integral of f(x) if dF/dx = f(x).
3、Sufficient Condition of lim x→∞f(x)=0;
4、Discussing the requirement for lim form(x→∞)f(x)=0;
5、Extended Variational Inequality Induced by f(x)∈g(x);
6、the set of functions F(x) + C, where C is any real number, such that F(x) is the integral of f(x).
7、On Uniform Continuity of f(x) on a Set D;
8、Function Models Like f(x)=ax~m+b/x~n+c;
9、The Value Fields of Rational Function y=f(x)/g(x);
10、"A periodic function repeats values over fixed intervals. If f(x + k) = f(x) for any value of x, f is a periodic function with a period of length k (a constant). The trigonometric functions are periodic. "
11、The function f in the y=f(x) equation that is behind that graph is how scalable your application is.
12、The proved method of function of f(x) in the section I of non-consistence;
13、a variable in a logical or mathematical expression whose value determines the dependent variable; if f(x)=y, x is the independent variable.
14、the function obtained by expressing the dependent variable of one function as the independent variable of another; f and g are inverse functions if f(x)=y and g(y)=x.
15、週期函數在固定間隔內有重覆的值。如果在x代表任何數值時f(x + k)= f(x),f即是以長度k(常數)為週期的週期函數。三角函數是週期*的
16、"The symbols f(x) and g(x) are typically used for functions of the independent variable x. A multivariable function such as w = f(x, y) is a rule for deriving a single numerical value from more than one input value. "
17、"在典型情況下,f(x)和g(x)的符號用於自變數x的函數。像w = f(x, y)這樣的多元函數,是從一個以上輸入值獲得單一數值的規則"
18、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.
19、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。
20、a variable in a logical or mathematical expression whose value depends in the independent variable; if f(x)=y, y is the dependent variable.
21、如果你有一个像钟形的分布，这是x，我得把它画得像对称的，尽管可能并不完美，这是f(x)，正态分布。
22、指数函数去哪儿了？面瘫张峰你是趁我在课堂上发呆的时候把它们杀了吗？！张峰驾着一辆log和f(x)的马车飞驰而去，我穿着拖鞋在后面边哭边追。
23、趋势：某件事发展或改变的大致方向。分为硬趋势、软趋势。硬趋势借用数学中的函数的概念。一个函数y=f(x)，对应的x=x1, 则y为y1，x=x2, 则y为y2……。其中硬趋势函数关系为y=f(x)确定的，软趋势则依据自变量的不同，导致的变量不同。（x1, y1），(x2, y2)……周期*变化：周而复始，循环往复，更多的是一个闭环。如春夏秋冬、生长收藏、水的蒸发和沉降……线*变化：只往单一方向发展，更多的是螺旋*上升。如思维的发展、电脑运算速度、标准……
