If the highest exponent of independent variable(say x) is 2 and the highest exponent of dependent variable(say y) is 1 and x and y are not multiplied, then the function is quadratic. For example: 3x-y+x2= 2y-5x+7 represents a quadratic function but y= xy+x2+5 doesn't represent a quadratic function.
You have to use the independent and the dependent variable. Commonly, x and y are used for the variables, but could be a and b or any two symbols or characters.
It seems part of this question is missing. Perhaps the answer is that you might compare the effect to basic functions such as linear, quadratic, or exponential.
It is a quadratic relationship which for every x, y is squared.
Yes.
Well, it's a non-linear relationship. It could be inverse, or quadratic, or many other things.
A quadratic relationship is a mathematical relationship that can be expressed by a quadratic formula in which the highest exponent is two (i.e., x squared). On a graph, this relationship will look like a parabola.

y=x squared
something that has the same ralationship
Yes.

Quadratic Relationship
a linear relationship is characterized by the form y=mx+b and a quadratic relationship is characterized by the form y=x^2+bx+c. Graphically represented, a linear equation forms a line and a quadratic will appear as a parabola.
Yes.
