a. For functions f and g in Figure 1-8g, identify how the pre-image function f (dashed) was transformed to get the image function g (solid). Write an equation for g(x) in terms of x given that the equation of f is Confirm the result by plotting the image and the pre-image on the same screen. b. If g(x) = 3f(x 4), explain how function f was transformed to get function g. Using the pre-image in Figure 1-8h, sketch the graph of g on a copy of this figure. R
