Does this have a graph?WHY?
I am using trig.

No. With real numbers, x^2 and y^2 are always positive.
Thus no solution.

No it has no real graph, because any real x^2 and y^2 are positive and -4 is negative. Adding two positive numbers will never result in a negative one.
Sorry about the confusion, I misread your original problem.

this will have a shape of a circle with radius of 2. you can draw it on a piece of paper. if x is 0 then y is 2 or -2. if y is 0 then x is 2 or -2.

that makes no sense ... example: (-2)^2 = 4 or (-9)^2 = 81, so adding to positive numbers the result will always a positive number

This does not have a graph because left hand side is positive and right hand side is -ve

x² + y² = â- 4
The - 4 under the radical sign. no real number solution is possible.
