3. Consider the two functions below: F(x) = 2cos(xx) Gujx) = %cos(2x) Part I: What are the amplitudes of the two functions? (4 points) Part II: What are the periods of the two functions? (4 points) Part III: Draw sketches of at least two periods of the two graphs, labeling each of the graphs. You may have to approximate the critical points of one of the graphs. (8 points) Part III: Draw sketches of at least two periods of the two graphs, labeling each of the graphs. You may have to approximate the critical points of one of the graphs. (8 points) For the functions below, state the amplitude, period, phase shift, and vertical translation of the graph for the sinusoid. (8 points for each question)
