Answer 3

Answer 4

oh wait those are absolute value signs?
nevermind haha

Answer 5

Yes those represent absolute value signs.

Answer 6

ok so normally that would equal a circle with a radius of square root of 1
but in this case we only want the positive values of that circle
which means both x and y must be positive

Answer 7

so theres our circle but we have to eliminate any spots where x or y is negative
so only the first quadrant works
and the radius is 1
