How about the distance travelled when you are accelerating at a constant rate? eg falling under the influence of gravity?
dunctions are not set equal to a value
what is the relationship between chest circumference and lung function test
Suppose the roots a quadratic, in the form ax2 + bx + c = 0, are p and q. Then p + q = -b/a and pq = c/a
A function.

A linear function is a line where a quadratic function is a curve. In general, y=mx+b is linear and y=ax^2+bx+c is quadratic.
Both are polynomials. They are continuous and are differentiable.
A mapping, perhaps. It need not be a function. The square root of a number, for example is a mapping but not a function (it is one-to-many). It is not correlation because correlation is only a measure of a LINEAR relationship. If two variables have an even relationship (eg quadratic), the correlation between two symmetric points will be 0 even though there is a clear functional relationship.
A quadratic function is a function where a variable is raised to the second degree (2). Examples would be x2, or for more complexity, 2x2+4x+16. The quadratic formula is a way of finding the roots of a quadratic function, or where the parabola crosses the x-axis. There are many ways of finding roots, but the quadratic formula will always work for any quadratic function. In the form ax2+bx+c, the Quadratic Formula looks like this: x=-b±√b2-4ac _________ 2a The plus-minus means that there can 2 solutions.
They are both polynomial functions. A quadratic is of order 2 while a cubic is of order 3. A cubic MUST have a real root, a quadratic need not.
A quadratic equation is wholly defined by its coefficients. The solutions or roots of the quadratic can, therefore, be determined by a function of these coefficients - and this function called the quadratic formula. Within this function, there is one part that specifically determines the number and types of solutions it is therefore called the discriminant: it discriminates between the different types of solutions.
