Question 937719: Determine which of the equations define a function with independent variable x. For those that do, find the domain. For those that do not, find a value of x to which there corresponds more than one value of y.

Determine which of the equations define a function with independent variable x. For those that do, find the domain. For those that do not, find a value of x to which there corresponds more than one value of y.
2x + ǀyǀ=7
------
Not a function because for some value of "x", y has 2 values.
Example::
If x = -7, |y| = 7+ 14 = 21
Then y = 21 of y = -21
