Function: F=9/5 * (x) +32

How would I explain that this is a function?

9(5)=45/5=9+32=41
9(10)=90/5=18+32=50
9(15)=135/5=27+32=59
9(20)=180/5=36+32=68
9(25)=225/5=45+32=77
9(30)=270/5=54+32=86
9(35)=315/5=63+32=95
9(40)=360/5=72+32=104

Uhhh... It's a function because it is. You get a different element for every element you plug into the equation.
