Best Answer

It is a function of the form D = ax + b where a and b are some constants and x is a variable which is linearly related to the demand. x could be the price of the goods in question, or be the price of a complementary good, a substitute, or it could be income, or time. Also, a linear relationship does not mean a causal relationship.

What is linear demand function and it relevant to a firm?

A linear demand function means that any change in the price of the output will have the same effect on the quantity demanded, whatever the price was. It has little relevance to a firm since the demand function is never really linear.


Why demand curve is convex?

Convex function on an open set has no more than one minimum. In demand it shows the elasticity is linear after some point and non linear on other points.

Explain the details of Linear Demand function equation?

Linear Cost Function A linear cost functionexpresses cost as a linear function of the number of items. In other words, C = mx + bHere, C is the total cost, and x is the number of items. In this context, the slope m is called the marginal cost and b is called the fixed cost.


Is linear function the same as linear equations?

No a linear equation are not the same as a linear function. The linear function is written as Ax+By=C. The linear equation is f{x}=m+b.

Is an exponential function linear?

No. An exponential function is not linear. A very easy way to understand what is and what is not a linear function is in the word, "linear function." A linear function, when graphed, must form a straight line.P.S. The basic formula for any linear function is y=mx+b. No matter what number you put in for the m and b variables, you will always make a linear function.
