Use the Leading Coefficient Test to Determine the End Behavior $1994 - 1998$

question 7

Multiple Choice

Use the Leading Coefficient Test to determine the end behavior of the polynomial function. Then use this end
-The following table shows the number of DWI arrests in a county for the years $1994 - 1998$ , where 1 represents 1994, 2 represents 1995, and so on.


This data can be approximated using the third-degree polynomial
$$\mathrm { T } ( \mathrm { x } ) = - 0.65 \mathrm { x } ^ { 3 } + 0.59 \mathrm { x } ^ { 2 } + 59.86 \mathrm { x } + 4832$$
Use the Leading Coefficient Test to determine the end behavior to the right for the graph of T. Will this function be useful in modeling the number of DWI arrests over an extended period of time? Explain your answer.

• A) The graph of T decreases without bound to the right. This means that as \(x\) increases, the values of \(T\) will become more and more negative and the function will no longer model the number of DWI arrests.
• B) The graph of \(T\) increases without bound to the right. This means that as \(x\) increases, the values of \(T\) will become large and positive and, since the values of T will become so large, the function will no longer model the number of DWI arrests.
• C) The graph of \(T\) approaches zero for large values of \(x\). This means that \(T\) will not be useful in modeling the number of DWI arrests over an extended period.
• D) The graph of T decreases without bound to the right. Since the number of larceny thefts will eventually decrease, the function T will be useful in modeling the number of DWI arrests over an extended period of time.

Hygiene Hypothesis

The theory that a lack of early childhood exposure to infectious agents, symbiotic microorganisms, and parasites increases susceptibility to allergic diseases by suppressing natural development of the immune system.

Cesarean Delivery

A surgical procedure used to deliver a baby through incisions in the abdomen and uterus, often used when a vaginal delivery would put the baby or mother at risk.

Childhood Asthma

A chronic inflammatory condition of the airways in children, characterized by recurring episodes of wheezing, coughing, and difficulty breathing.

Hygiene Hypothesis

A theory suggesting that a lack of early childhood exposure to infectious agents, symbiotic microorganisms (such as those found in the gut), and parasites increases susceptibility to allergic diseases by suppressing the natural development of the immune system.
