Lesson 2-3B : FUNCTIONS

A Function is a relation in which each member of the domain (input value) is paired with exactly one member of the range (output value). Functions are often written as Equations, for example: F(x) = 25x.  Where F(x) is where the input will be entered and 25x is where the output will come out. Check the image below
