funktsioonimärke
Funktsioonimärke, often translated as function notation or functional notation, is a convention used in mathematics to represent the relationship between input and output values of a function. Instead of using expressions like y = 2x + 1, function notation uses f(x) = 2x + 1. Here, 'f' represents the name of the function, and '(x)' indicates that 'x' is the input variable. The expression 'f(x)' is read as "f of x" and signifies the output value of the function 'f' when the input is 'x'.
This notation offers several advantages. It clearly distinguishes between the function itself and its output value,
Function notation is fundamental in calculus, algebra, and many other mathematical fields, providing a concise and
