Which relation could be rewritten using function notation a) x=3 b) x+y=3 c) x+y^2=3 d) x^2 + y^2=3

For this case we have, by definition, a function is given in the form:

Where x is the independent variable and y is the dependent variable.

If we have:

We can rewrite it in the following way:

Comparing with the generic definition of a function, we have that

A relation that could be rewritten using function notation is option b.
