Function(By Jasmine, Kang Xiong and Ada)

What is a function?

A function is a rule which relates the values of one variable quantity to the values of another variable quantity, and does so in such a way that the value of the second variable quantity is uniquely determined by (i.e. is a function of) the value of the first variable quantity.

What is the relationship between x&y?
 x  the independent variable and  y  the dependent variable.

Is function a relation?
It is a relation as it has at least 2 variables with one of them depending on the other variable.
