Y = 25 + 5x
let x = 1
then
y = 25 + 5(1) = 30

let x = 3
then
y = 25 + 5(3) = 40

 linear function is under polynomial function,
its characteristic is slanting line when you draw a graph
            example
  f(x)=2x+5
the domain is {x|x is a real number}
the range is {y|y is arel number}
    thats it....
