Which relation could be rewritten using function notation? a) x = 3 b) x + y = 3 c) x + y2 = 3 d) x2 + y2 = 3

x=3

Step-by-step explanation:

a function means that its proportional

So D wouldn't be the answer

Neither would C

And you can't add a variable together to get a number

The answer would be A because x=3 would be logical

hope this helps

step-by-step explanation:

y = | -2(-2) |     →     y = | 4 |     →     y = 4       ⇒   (-2, 4)

y = | -2(-1) |     →     y = | 2 |     →       y =   2       ⇒   (-1, 2)    

y = | -2(0) |     →     y = | 0 |     →       y = 0         ⇒   (0, 0)

y = | -2(1) |   c →     y = | -2 |     →     y =   2         ⇒   (1, 2)    

y = | -2(2) |     →     y = | - 4 |     →     y =   4         ⇒   (2, 4)
