- Problem 5 Find the domain and range of the following functions. 1. The function that assigns to each pair of positive integers the first integer of the pair. 2. The function that assigns to each positive integer the largest perfect square not exceding this integer. 3. The function that assigns to a bit string the number of ones minus the number of zeros in the string. 4. The function that assigns to each pair of positive integers the the minimum of these two integers. Solution:arrow_forwardConsider the data shown below. Enter this data into the calculator under STAT as L1 and L2. In the past, we have done Linear Regression and, more recently, Quadratic Regression. This time, we are going to try to fit a cubic polynomial to this data. Is it possible that a cubic function fits the data well? Let's find out. Use the data in the given table to fill in the missing coefficients. Use your calculator and use the CUBIC REGRESSION command on the STAT key (CubicReg). Round your answers to 3 decimal places. -4 . -576.24 -0.5 31.85 3 6.5 36.75 10 845.152 13.5 3133.305 17 7761.6 +. y = How well does the cubic polynomial function fit the data? Choose the best answer. OIt does not fit the data well at all. OThe cubic polynomial fits the data points very well because the value of R 2 is quite close to 1. OI drew the graph and it fits well, I think. OLet me ask my Dad; He knows everything. OI have no idea.arrow_forwardExample: Test Scores and Class Size sw Section 9.4 Test score 740 Test score 780 Linear regression 720 Linear-log regression 760 Linear-log regression 700 740 680 Cubic regression 720 Cubic regression 700 660 680 640 660 620 640 600 620 10 20 30 40 50 60 10 20 30 40 50 District income District income (thousands of dollars) (thousands of dollars) • = (MA, CA) for TestScore vs Income (Left, Right) They are similar: the relationship is steeper for low value of income • Best functional forms differ (Cubic for MA, Linear-log for CA)arrow_forward
