Question

F(x) = 4/9x + 7
linear or nonlinear?

Answer 1

It depends on what you meant. See below.

Explanation:

What you wrote means this:

`f(x) = (4)/(9)x + 7`

This is linear.

If you meant this

`f(x) = (4)/(9x) + 7`

or this

`f(x) = (4)/(9x + 7)`

then it's non-linear.

An x in the denominator makes a function non-linear.

Answer 2
