The equation is -x2 - 4 = 14 or -x2 = 18 which is the same as x2 = -18. That is the quadratic equation.
If you mean y = x2, then yes, it is nonlinear.
Type your answer here. Find the radius for a circle with the equation x2 plus y2 equals 9? ..
-4 and 4
x2 + y2 = 2r2
If: x2 = 3 Then: x = square root of 3

5. A circle with centre (0,0) has equation: x2 + y2 = radius2 With: x2 + y2 = 25 = 52 The radius is 5.
x2 = 81 Square root both sides:- x = +/- 9
Equation of a circle centre the origin is: x2 + y2 = radius2 ⇒ radius = √9 = 3.
the graph is moved down 6 units
Divide both sides of the equation by x: x2 = 9x x2 / x = 9x / x x = 9
