(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

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

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