Understanding linear functions

Some values for a function are shown in the table.

Which statement best describes the function?

• it is linear because f(x) increases by a constant amount compared to x.

• it is linear because f(x) increases by a constant percentage compared to x

• it is not linear because f(x) does not increase by a constant amount compared to x

• it is not linear because f(x) does not increase by a constant percentage compared to x.
