Use a graphing utility to graph the three functions in the same viewing window. f(x) = x - 3x + 2 g(x) = -f(x) h(x) = f(3x) Describe the graph of g relative to the graph of f. O g(x) is a reflection in the y-axis. O g(x) is a horizontal shrink. O g(x) is a reflection in the x-axis. O g(x) is a horizontal stretch. Describe the graph of h relative to the graph of f. Oh(x) is a reflection in the x-axis. Oh(x) is a reflection in the y-axis. Oh(x) is a horizontal stretch. Oh(x) is a horizontal shrink.
