This week we learned about function notation.

Function notation looks something like this:

F(x)= 6x-9

Function notation is another way of showing the value of y in a function because F(X)= Y

So if F(6)

Then our equation would be

F(6)= (6)(6) – 9

Which is

F(6)=36-9

F(6)=27

so 27 is the value of Y.
