Consider the function represented by 9x + 3y = 12 with x as the independent variable. How can this function be written using

function notation?

Fly) = -

f (x) = - 3x + 4

f (x) =

FCV) = - 3y + 4

f (x) = - 3x + 4

Step-by-step explanation:

Step 1: Write it in slope-intercept form

9x + 3y = 12

3y = - 9x + 12

y = - 3x + 4

Step 2: Replace y with f (x)

f (x) = - 3x + 4

In math, function f (x) is equal to the variable y.
