Consider amplitude, period, and shifts. f(x) = cos 4x g(X) = 2 + cos 4X 0 The graph of g has an amplitude 2 times that of the graph of f. O The graph of g is a horizontal shift of the graph of f2 units to the right. 0 The graph of g is a vertical shift of the graph of f2 units downward. O The graph of g is a reflection of the graph of fin the yaxis. O The period ofg is 2 that of 1'. Need Help? 6. [-/1 Points] DETAILS LARPCALC10 4.5.022. Describe the relationship between the graphs of f and g. Consider amplitude, period, and shifts. 4 X O The amplitude of g is one-half the amplitude of f. O The amplitude of g is 2 times the period of f. O The period of g is one-half the period of f. O The graphs of f and g differ only in their phase shift. O The period of g is 2 times the period of f.
