what is a funtion . short answer
Answers
Answer:
A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output. Every function has a domain and codomain or range.
Answer:
A technical definition of a function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output. ... We can write the statement that f is a function from X to Y using the function notation f:X→Y.
function and its type_ We can define a function as a special relation which maps each element of set A with one and only one element of set B. Both the sets A and B must be non-empty. A function defines a particular output for a particular input.
basic function_ The basic polynomial functions are: f(x)=c, f(x)=x, f(x)=x2, and f(x)=x3. The basic nonpolynomial functions are: f(x)=|x|, f(x)=√x, and f(x)=1x. A function whose definition changes depending on the value in the domain is called a piecewise function. The value in the domain determines the appropriate definition to use.
