5. Let f(x) = 4^x. For each function that follows, • state the transformations that must be applied to f(x)
• state the y-intercept and the equation of the asymptote
sketch the new function
• state the domain and range
a) g(x) = 0.5f(-x) + 2
c) g(x) = – 2f (2x – 6)
b) h(x) = -f(0.25x + 1) - 1 d) h(x) = f(-0.5x + 1)

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.
