QuestionWrite the function $9x + 3y = 12$ in function notation as $f(x)$.

Studdy Solution
Now that we have $y$ alone on one side of the equation, we can rewrite the equation using function notation. In function notation, $y$ is replaced with $f(x)$.
$$f(x) = -3x +4$$So, the function $9x +3y =12$ can be written using function notation as $f(x) = -3x +4$.
