Represents A Function Math
Use function notation to represent a function whose input is the name of a month and output is the number of days in that month.
Represents a function math. I set of ordered pairs. A b be a function defined by f x x 2 1 where a 2 4 6 10 12 b 0 1 2 4 5 9. Function in mathematics an expression rule or law that defines a relationship between one variable the independent variable and another variable the dependent variable. Functions are ubiquitous in mathematics and are essential for formulating physical relationships in the sciences.
We could even say that x as a function of y is equal to y squared plus 3. The number of days in a month is a function of the name of the month so if we name the function f we write text days f text month or d f m. Now let s see if we can do it the other way around if we can represent y as a function of x.
