The polynomial function with rational coefficients has roots of: –2, √3, and - √3. what is the equation? f(x)= (x + 2)(x - 2)(x + √3) a (x + 2)(x +√3)(x - √3) b (x - 2)(x +√3)(x - √3) c (x + 2)(x - 2)(x + √3)(x -√3) d

17. a researcher measures three variables, x, y, and z for each individual in a sample of n = 20. the pearson correlations for this sample are rxy = 0.6, rxz = 0.4, and ryz = 0.7. a. find the partial correlation between x and y, holding z constant. b. find the partial correlation between x and z, holding y constant. (hint: simply switch the labels for the variables y and z to correspond with the labels in the equation.) gravetter, frederick j. statistics for the behavioral sciences (p. 526). cengage learning. kindle edition.
