Consider the function represented by 9x + 3y = 12 with x as the independent variable. How can this function be written using
function notation?
FO==
+
f(x) = -3x+4
F()=
x+
f(V) = -3y+4

Respuesta :

Answer:

f(x) = - 3x + 4

Step-by-step explanation:

Note that y = f(x)

Given

9x + 3y = 12 ← rearrange making y the subject

Subtract 9x from both sides

3y = - 9x + 12 ( divide all terms by 3 )

y = - 3x + 4, that is

f(x) = - 3x + 4
