Activity Example Lesson 22

1) When to use linear equation modeling if given with a data set from two variables?

• A) If the created scatterplot appears to be a straight line.
• B) If the created scatterplot appears to be a curved line or a U-shaped path or an inverted U-shaped path.

2) When to use quadratic equation modeling if given with a data set from two variables?

• A) If the created scatterplot appears to be a straight line
• B) If the created scatterplot appears to be a curved line or a U-shaped path or an inverted U-shaped path.

3) What is the structure of the Linear Model in Desmos graphing calculator?

• 
• 

4) What is the structure of the Quadratic Model in Desmos graphing calculator?

• 
• 

5) What type of equation model is appropriate for the data set given below? Provide reason.

• A) LINEAR Model because the created scatterplot appears to be a straight line
• B) QUADRATIC Model because the created scatterplot appears to be a curved line or a U-shaped path or inverted U-shaped path.

6) What should be the equation model for the given data set shown below?

• A) y = -233x + 489, 302
• B) y = -5.6643x^2 - 233x + 489, 302

7) What will be the expected population of Warren County by the year 2024?

• A) 17, 017
• B) 17, 170
• C) 17, 107
• D) 17, 710

8) What do you think are the reasons why the population of Warren County keeps on decreasing? Note: Multiple answers are allowed

• A) Death due to old age and sickness.
• B) It has lesser working opportunities so the younger generations transferred to neighboring counties or states with a lot of working opportunities.
• C) The common nature of work is agricultural and the inclination of the younger generations are not into agricultural so they opted to transfer to different places with working opportunities that matched with their interests.
• D) Other reasons. (Note: Write it on your worksheet)

9) What recommendations can you propose so that the population of Warren County will not continually decrease over time? Note: Multiple answers are allowed

• A) Offer agricultural related incentives to younger generations so that they could start to love agricultural related works.
• B) Offer housing related incentives to younger generations with a condition that they should take programming courses and offer them programming related jobs within the vicinity of Warren County so that they will stay.
• C) Create multiple working opportunities for them like data science, cybersecurity, web development, and programming with incentives from the government if they would stay within the vicinity of Warren County.
• D) Conduct a survey as to what is the highest type of working preference of the younger generations and create a doability model pertaining to the availability of that job. Then offer them with incentives.

10) What type of equation model is appropriate for the data set given below? Provide reason

• A) LINEAR equation model because the created scatterplot appears to be a straight line.
• B) QUADRATIC equation model because the created scatterplot appears to be a curved line or a U-shaped path or inverted U-shaped path
