Explanation The amount of waste per person consists of industrial waste, sewage waste and demolition waste. Now it is given the data for amount of waste per person as per the year. Year 1980 1985 1990 1991 1992 1993 1994 1995 1996 2001 Pound of waste per person 3.7 3.8 4.5 4.4 4.5 4.5 4.5 4.4 4.3 4.4 Now we plot the graph below, Here we can see that the graph initially increases and then decrease and then increase. So it changes direction two times. So it is a cubic function. But the model can vary and give wrong result because the scattered plot is very close to each other and also there not too many points to get an accurate result. So the amount of waste may vary.

Equations and Inequations

Equations and inequalities describe the relationship between two mathematical expressions.

Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Chapter 4.8, Problem 3CFU

To determine

The reason for which the amount of waste per person may vary.

Expert Solution & Answer

Explanation of Solution

The amount of waste per person consists of industrial waste, sewage waste and demolition waste. Now it is given the data for amount of waste per person as per the year.

Year	1980	1985	1990	1991	1992	1993	1994	1995	1996	2001
Pound of waste per person	3.7	3.8	4.5	4.4	4.5	4.5	4.5	4.4	4.3	4.4

Now we plot the graph below,
