You can specify arbitrary functions as a string with theinlinecommand and pass them to the function function routines, but this command is difficult to use, particularly to separate the many different types of parameters, including the arguments to the inlined function and the function ...

Compositions of Functions, Even and Odd Functions, Extrema, Absolute and Relative Minimum and Maximum, Domain and Range of Compositions
swap the x"s and y"s: x = 2y + 1 Make y the subject of the formula: 2y = x - 1, so y = ½(x - 1) Therefore f-1(x) =½(x - 1) f-1(x) is the standard notation for the inverse of f(x). The inverse is said to exist if and only there is a function f-1wi...
In other words, restrict it to x ≥ 0 and then we can have an inverse. So we have this situation: x2 does not have an inverse but {x2 | x ≥ 0 } (which says "x squared such that x is greater than or equal to zero" using set-builder notation) does have an inverse.No...
Functionstypically manipulate data and return a result. You can also create user-defined functions (UDFs), sometimes referred to as custom functions. Functions have the following general form: functionName([argument1[, argument2]]...) Some functions, such as the Now function take no arguments....
Calculates the corresponding ISO8601 string using UTC Z notation for a given date and time (not adjusted for local time zone). Now Calculates the current date and time in various formats, all in UTC time (not adjusted for local time zone). Subtract Subtracts a multiple of a unit of ...
Writing the inverseNotationThe graph of an inverse functionHERE IS the definition of functions being inverses:Functions f(x and g(x) are inverses of one another, means: f(g(x)) = x and g(f(x)) = x, for all values of x in their respective domains....
Returns a geometry that represents the point set symmetric difference of the geometry values g1 and g2, which is defined as: g1 symdifference g2 := (g1 union g2) difference (g1 intersection g2) Or, in function call notation: ST_SymDifference(g1, g2) = ST_Difference(ST_Union(g...
