what kind of relationship between variables is described by a quadratic equation?

Question

I'd  like a more practical answer...like dependent relationship, or inverse relationship...if there IS such a thing, for quadratic equations.

Answer 1

In a quadratic equation, the relationship between the x variable and y variable varies.  This is because you can have more than one x value that equals the same value of y.  Unlike linear equations, only one x value equals a certain y value.  Quadratic equations travel in both directions in the dependent variables as the independent variable travels in one direction.
