Not all relations are function but all functions are relation. A good example of a relation that is not a function is a point in the Cartesian coordinate system, say (2, 3). Though 2 and 3 in (2, 3) are related to each other, neither is a function of the other. Function is a ...
若有一函數 f 代表 X→Y,則其反函數 f⁻¹ 就是 Y→X,可以有反函數的函數稱為「可逆函數(invertible function)」,所有可逆函數必為雙射函數。 在下圖中,f(x) 與 f⁻¹(x) 互為反函數關係、g(x) 與 g⁻¹(x) 亦互為反函數關係。對於 f(x) 及 g⁻¹(x) 而言,藍色區域為定義域...

Answer and Explanation: The difference between relation and function is the same if it is a continuous domain or whether it is discrete domain. To be a function each x value gives one y value you. Just because the x value is isolated it doesn't change the requirement to be a ...
However, in exploring math itself we like to maintain a distinction between a function such as ff, which is a rule or procedure, and the output yy we get by applying ff to a particular input xx. This is why we usually use notation such as y=f(x),P=W(d)y=f(x),P=W...

MySQL provides several MySQL-specific functions that test the relationship between minimum bounding rectangles (MBRs) of two geometriesg1andg2. The return values 1 and 0 indicate true and false, respectively. The bounding box of a point is interpreted as a point that is both boundary and interior...
