# Types of mapping function

Quadratic functions. These are functions of the form: y = a x 2 + b x + c, where a, b and c are constants. Their graphs are called parabolas. This is the next simplest type of function after the linear function. Falling objects move along parabolic paths.

Additional properties of the source object: mapChar - specifies the mapping char. By default it is '>'. In the following code, if the mapChar was set to '.', we should use '.' instead of '>' to specify the fields map. Figure (i) is a violation of the definition of the function. The given function does not map every element of A. Question 2: What is meant by function and what are its types? Answer: A function refers to a special relation which maps each element of one set with only one element belonging to another set. The various types of functions are as ...Decimal type values are numeric values with fixed decimal precision and scale. Precision is the number of digits that the number contains. Scale is how many of these digits appear after the decimal point. This type can represent decimal fractions exactly, and is suitable for financial calculations.In Java 8, Function is a functional interface; it takes an argument (object of type T) and returns an object (object of type R). The argument and output can be a different type.

arg : function, dict, or Series na_action : {None, 'ignore'} If 'ignore', propagate NA values, without passing them to the mapping correspondence.na_action checks the NA value and ignores it while mapping in case of 'ignore'. Return type: Pandas Series with same as index as caller. Example #1: In the following example, two series are made from same data. pokemon_names column and ...
