Linear function may not be adequate for describing the supply and demand functions.
Step-by-step explanation:
We have to explain why a linear function may not be adequate for describing the supply and demand functions.
Linear functions are extremely simple functions
They are of the form:
Linear function is straight line function with one dependent anf one independent variable.
Supply and demand function is a complicated function and phenomenon and thus, linear functions cannot be used to approximate supply and demand.
The supply and demand function cannot be adequately described by linear function due to its simplicity.
Other functions that can be used to describe supply and demand function are quadratic function, functions with higher degree polynomials, exponential functions based on factors like time and place, etc.
It the rate of change is not constant then it would mean change in slope which cannot be described by a linear function.
