The same thing would be true for the first function above, f(x) = x²: n² would equal n.This would be a weird mathematics indeed (there are algebras in which this happens for some nonunit ...

A linear demand function is an algebraic formula for calculating demand curves without having to draw a demand function graph. There is no standard way of writing down a demand function, ...

Nonlinear regression is a form of regression analysis in which data is fit to a model and then expressed as a mathematical function. Simple linear regression relates two variables (X and Y) with a ...
