30、st function? Briefly explain the three ways that a linear cost function may behave? Answer: The two usual assumptions behind a simple linear cost function are:1) Variations in the level of a single activity (the cost driver) explain the variations in the related total costs; and2) Cost behavior is a

31、pproximated by a linear cost function within the relevant range. This means that total cost versus the level of a single activity that is related to that cost is a straight line within the relevant range. Once linearity is established, there are three possible types of linearity:1) A strictly variab

32、le cost of the form Y = bX, where b is the slope of the straight line and is the variable cost per unit of the cost driver;2) A strictly constant cost of the form Y = a, where a is the total fixed cost or constant; and3) A mixed or semivariable cost of the form Y = a + bX, where a is the total fixed

33、 cost or constant, and b is the variable cost per unit of the driver or the slope of the straight line.
