Question 689023: What is a function?

You can put this solution on YOUR website!

It is like a machine that has an input and an output, and the output is related somehow to the input.
f%28x%29 = .........is the classic way of writing a function
The most common name is "f", but you can have other names like "g" or whatever you want to name it.
Sometimes a function has no+name, and you might just have:
y+=+x%5E2
but there is still:
an input... (x)
a relationship.... (squaring)
and an output...... (y)
