The tCharlie used a regression calculator to generate the equation f(x) = –0.15x 20.1 for the ordered pairs (2, 15), (4, 21), (6, 26), (8, 20), and (10, 14). Is a linear representation the best way to represent the data? If it is, explain why. If not, explain why and suggest a better alternative.able below shows the height of a ball x seconds after being kicked. What values, rounded to the nearest whole number, complete the quadratic regression equation that models the data? f(x) = ____ x^2 _____ x 0 Based on the regression equation and rounded to the nearest whole number, what is the estimated height after 0.25 seconds? ____ feet
