Question

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

Answer 1

\[9x= 12- 3y\] Subtract the 3y from both sides

Answer 2

\[x= 12/9-3y/9\] Divide 9 by both sides

Answer 3

f(x)_____x+4

Answer 4

\[f(x)= 4/3 -1/3y\] Simplify
