Charles uses a graphing calculator to find a quadratic regression model f for a given set of data. When he compares model f to a
n earlier regression model g for the same data, he determines that g more accurately models the data. Which of the following statements are true? Select all that apply. A. Function f likely had fewer residuals near the x-axis than function g.
B. Function f likely had more residuals equal to 0 than function g.
C. Function g had more residuals near the y-axis than function f.
Step-by-step explanation: If you subtract each price by the price lower then it. Ex: $19.95 - $15.96 = $3.99, $15.96 - $11.97 = $3.99 and so on. They all equal $3.99.
Discriminant = sq root (-17^2 -4*3*10) discriminant = sq root (289 -120) discriminant = sq root (169) The discriminant is positive so the equation will have 2 rational solutions.
