What is a function?

Done by: Bryan Sim and Harindrar s/o Jayanthinathan
1. What is a function?
A function is an equation. A function is like a machine: it has an input and an output.

2. What is the relationship between x and y?
Any x that can be plugged into the equation will yield exactly one y out of the equation.

3. Is the function a relation?
Yes. The output is related somehow to the input.
