The main difference between an equation and a function is the fact that an equation usually deals with a single input, whereas, a function can have numerous inputs. In mathematics, an equation is used to denote the equality between two expressions.
In simpler terms, the value of an equation is determined by the value the expressions are equated with, while the value of a function depends on the value of âXâ assigned. To make it clearer, students should understand that a function gives the value and defines the relationships between two or more variables.
