WebA cautionary note: Economists are accustomed to designate all lines in graphs as curves - both straight lines and lines which are actually curved. Although the slope of a linear function is the same no matter where on the line it is measured, the slope of a non-linear function is different at each point on the line. WebYes, you can use transformations to include some nonlinear functions into a linear model. But, you have to be able to express those functions in a linear form. See the example of using log functions in my post about …

WebExcel has a preprogrammed feature that will find the best fitting equation for a data set for a select number of functions: We will show how to find an equation for a data set, assuming we know what model would be the best one to represent the data. Example 1.5.1. Best fitting linear curves. Figure 1.5.2. WebNow the demand function can be written as; Q X =60-4P x. This demand function also can be written as: 4P x =60-Q X. P x = (60-Q X)/4. So P x = 15-0.25Q X which is known as an inverse demand function. Non-linear Demand Function. If the slope of demand curves changes all along the demand line then it is said to be non-linear or curvilinear. flame resistant outerwear
