Question

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

The relation that can be rewritten using function notation is x = 3.

Step-by-step explanation:

A relation that can be written using function notation will have a single, unambiguous output for each input. Function notation is typically represented as f(x), where x is the input value and f(x) is the output value.

• A) x = 3 does not have an output value, so it cannot be written using function notation.
• B) x + y = 3 is a linear equation, but it is not in the form of a function as it has two variables.
• C) x + y2 = 3 is not a linear equation as it contains a quadratic term, y2.
• D) x2 + y2 = 3 is a nonlinear equation as it contains a quadratic term, x2.

Therefore, the relation that can be rewritten using function notation is A) x = 3.

Answer 2

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
