• Quadratic

• No Correlation

What type of regression model best describes the scatter plot shown?

• Quadratic

• Exponential

• No Correlation

The scatter plot shows the relationship between the number of chapters and the total number of pages for several books.  Use the trend line to predict how many chapters would be in a book with 180 pages. 

• 12 chapters
• 15 chapters
• 18 chapters
• 21 chapters

Use your calculator to determine the best LINEAR regression model of the function. Round to the nearest hundredth when necessary.

• y = 5x+1.82

• y = 4.2x + 1.1

• y = 1.82x + 5.02

• y = 1.1x + 4.2

Use EXPONENTIAL regression to find an equation that fits the​ data, where x is the years since 1990.

• y=8.92•1.23^x

• y=1.23•8.92^x

• y=4.9•1.23^x

• y=1.23•4.9^x

This table represents what kind of function?

This table represents which type of function?

• Linear

• Quadratic

• Exponential

• Cubic

Use your calculator to determine the best regression model (you need decide lin, quad or exp) of the function. Round to the nearest hundredth when necessary.

• y = 0.52x² - 12.25x + 99.81

• y = -9.05x + 97.14

• y = 100(0.88)^x

• y = 0.88(100)^x

• y = 97.14x - 9.05

Use your calculator to determine the best regression model (you need decide lin, quad or exp) of the function. Round to the nearest tenth when necessary.

• y = -1(4)ˣ

• y = 1x - 4

• y = -4x + 1

• y = -4x² + 1

• y = x² -4x + 1
