5.) (5 pts.) Let's calculate the regression equation for another data set. Clear the expression list and enter the following table. X 0 9.3 1 4.99 2 3.41 3 0.05 4 -2.89 In the expression list, enter y1~mx1 +b. You must include the tilde symbol. Write down the equation below. Also include a screenshot of your graph. 6.) (3 pts.) Do you think the equation is a good fit to the points? Justify your answer. 7.) (5 pts.) For the data in the table below, find a best fit quadratic function of the form y = ax +bx + c. In this problem, Desmos will find the values of a, b, and c that make the quadratic equation come as close as possible to the points in the table. To get the quadratic regression in Desmos, we use y1~axi +bx1 +c. Note that this assumes the x's are in a column labeled x1and the y's are in a column labeled y1. Write down the quadratic regression and a screenshot of your graph. -100 9803 -80 6243 -60 3483 -40 1523 -20 363 0 3 20 443 40 1683 60 3723 80 6563 100 10203 8.) (3 pts.) How can we tell by looking at the data that the quadratic regression will not match up with the points in the table
