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

function notation?

f (y) = - 1/3y+4/3

f (x) = - 3x+4

f (x) = - 1/3x + 4/3

f (y) = - 3y+4

Danielle Wiggins · Answer 1

You only have to write the expression for y and change y by f (x). This is:

9x + 3y = 12

3y = - 9x + 12

y = - 3x + 4

f (x) = - 3x+4

Then, the answer is B
