Question

How do you write `3x+2y=6` in function notation?

Answer 1

Function notation is (usually) of the form
`f(x) =` an expression in terms of `x`
where `f(x)` is a replacement for `y` in the standard form.

`3x+2y = 6`

`rarr 2y = 6-3x`

`rarr y = 3-3/2x`

`rarr f(x) =3-3/2x` (in function notation)
