Revise how to recognise and determine the equation of a quadratic function from its graph. BBC Bitesize Scotland revision for SQA National 5 Maths.

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 ...

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.

What happens when the floor function meets the quadratic equation? Replacing one or more occurrences of the variable in a quadratic equation with its floor results in diverse and interesting behavior.

Therefore, we propose using the quadratic function to approximate the slowness equation based on three known traveltime points in the local solver. Subsequently, we obtain two roots from the fitting ...
