One of the equations below is the equation of a circle.
Identify this equation.
Tick one box.
(x−2)2−(y+5)2=16(x - 2)^2 - (y + 5)^2 = 16(x−2)2−(y+5)2=16
(x−2)2+(y+5)2=−16(x - 2)^2 + (y + 5)^2 = -16(x−2)2+(y+5)2=−16
(x−2)2+(y+5)2=16(x - 2)^2 + (y + 5)^2 = 16(x−2)2+(y+5)2=16
(x−2)3+(y+5)3=16(x - 2)^3 + (y + 5)^3 = 16(x−2)3+(y+5)3=16
