We will see many ways to think about functions, but there are always three main parts: 1. The input 2. The relationship 3. The output
But we are not going to look at specific functions ... ... instead we will look at the general ideaof a function.
First, it is useful to give a function a name. The most common name is "f", but we can have other names like "g" ... or even "marmalade" if we want. But let's use "f": We say "f of x equals x squared" what goes intothe function is put inside parentheses () after the name of the function: So f(x) shows us the function is called "f", and "x" goes in ...
Don't get too concerned about "x", it is just there to show us where the input goes and what happens to it. It could be anything!
Sometimes a function has no name, and we see something like: y = x2 But there is still: 1. an input (x) 2. a relationship (squaring) 3. and an output (y)
At the top we said that a function was likea machine. But a function doesn't really have belts or cogs or any moving parts - and it doesn't actually destroy what we put into it! A function relatesan input to an output. Saying "f(4) = 16" is like saying 4 is somehow related to 16. Or 4 → 16
So we need something more powerful, and that is where setscome in: Each individual thing in the set (such as "4" or "hat") is called a member, or element. So, a function takes elements of a set, and gives back elements of a set.
But a function has special rules: 1. It must work for everypossible input value 2. And it has only one relationshipfor each input value This can be said in one definition:
When a relationship does not follow those two rules then it is not a function ... it is still a relationship, just not a function.
On a graph, the idea of single valuedmeans that no vertical line ever crosses more than one value. If it crosses more than once it is still a valid curve, but is not a function. Some types of functions have stricter rules, to find out more you can read Injective, Surjective and Bijective
Learn the definition, examples and types of functions in math. A function relates an input to an output and follows two rules: it covers every element of the input set and it is single valued.
