**1) What is a function?**

Is an expression to involve something into a relationship

x=5 f(x)=10

so f=2

eg: How the shape of line is depended on the function

**2) What is the relationship between x & y?**

x is an independant variable but y is a dependent variable as it depends on x

**3) Function a relation?**

Yes, With a function equation/expression we can find out how the line is related to the coordinates, or how the coordinates affect the function equation
