Using Desmos, create a quadratic regression model with your data. Take a screen shot of your model in Desmos and paste it in the show your work window.
Type out the Quadratic Model that represents your data.
What is the correlation coefficient for your Quadratic Model? This is the R Squared value.
Using Desmos, create a linear regression model with your data. Take a screen shot of your model in Desmos and paste it in the show your work window.
Type out the Linear Model that represents your data.
What is the correlation coefficient for your Linear Model? This is the R Squared value.
Which model do you think best matches your data? Justify your reasoning using the R Squared correlation coefficient.
What is the stopping distance if you are traveling 25 mph?
What is the stopping distance if you are traveling 75 mph?
What is the stopping distance if you are traveling 100 mph?
Suppose a car took 500 feet to brake. Use your model to calculate how fast the car was going when the braking began.
