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.
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.
It will just be the gradient of the function, which should be constant in a linear function.
It is a continuous function. If the line is a straight line, it is a linear function.
The inverse of a linear function is always a linear function. There are a few ways to approach this.To think about it, you can imagine flipping the x and y axes. Essentially this equates to turning the graph of the linear function on its side to reveal the new inverse function which is still a straight line.More rigorously, the linear function y = ax + b has the inverse equation x = (1/a)y - (b/a). This is a linear function in y.

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.
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.

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.
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.
Assuming the domain is unbounded, the linear function continues to be a linear function to its end.

As a linear function
it is impossible for a linear function to not have a y-intercept
Your age is a linear function (of time).
