(a) The graph of f(x) = (x + 12) can be obtained from shifting the graph of f(a) - ac to the 12 units. (b) The graph of f(a) = 2 + 12 can be obtained from shifting the graph of f(x) - x2 12 units. (c) The graph of f(x) = 12vx can be obtained from the graph of f(a) - Vac vertically by a factor 12. (d) The graph of f(x) = V12x can be obtained from the graph of f(a) = Vac horizontally by a factor For each question, enter one of: left, right, upward, downward, stretching, shrinking Check
