x n = y n
n x n = n y n
x = y , therefore a curve of any kind (including circle) is out of the question since the equation is linear
since even exponents turn any negative number into a positive number ( − m ) 2 = m 2 then − 1 2 = 1 2
1 2 = 1 2
− 1 2 = 1 2
1 2 = − 1 2
− 1 2 = − 1 2
same for 2
2 2 = 2 2
− 2 2 = 2 2
2 2 = − 2 2
− 2 2 = − 2 2
therefore, the answer is that it looks like an X
