It is a quadratic relationship which for every x, y is squared.
The domain of y = x2 is [0,+infinity]
If you mean y = x2, then yes, it is nonlinear.
x1:y1 = x2:y2 4:-2 = x2:5 x2 = (4*5)/-2 x2 = -10
No translation will invert a quadratic graph.
the graph is moved down 6 units
Y = X2 forms a parabola
y = 4x-3
Yes. Think of y as being a function of x. y = f(x) = x2 + 1

y = x2 + 4 The graph is a parabola, with its nose at y=4 on the y-axis, and opening upward.
x2 / y = (6)2 /2 = 36/2 = 18
y = x2 - 6x + 2 y = x2 - 6x + 9 - 7 y = (x - 3)2 - 7
