Quadratic equations are polynomials, meaning strings of math terms. An expression like “x + 4” is a polynomial. They can have ...

But how do you come up with a function to fit data? The basic idea is to create a quadratic function and vary the parameters such that the deviation of the actual data from the function is minimized.

The equation of a a quadratic function can be determined from a graph showing the turning point and another point on the graph. Brush up on your knowledge on how to recognise and determine the ...
