Question

(WORTH 20 POINTS) Which relation could be rewritten using FUNCTION notation?

A) x = 3
B) x + y = 3
C) x + y2 = 3
D) x2 + y2 = 3

Answer 1

B) can be rewritten in function notation.

To find the function we must isolate y. To do this, we must subtract x from each side which will give us
`y=3-x`

Now, we can replace y with f(x), so the function is

`f(x) =3-x`
