Question 6 Complete 2.50 points out of Boo 1)? Flag question Sketch the graph of x) = -2cos(21tx) and answer the questions below showing all algebraic steps: a) Find the amplitude of x). Describe what the amplitude tells you about the minimum or maximum of x). b) Find the period of x). Describe how you can use period of x) to nd the 5-key points of x). c) Describe all transformations that have taken place in comparison to the parent function x) = cos(x). d) Set up an table showing the 5key points. a) Graph one cycle of x). written on paper amplitude = 2 . it tells us that the max and min value is 2 and 2 respectively the graph is stretched by an amplitude of 2 and periodically 2 (repeated after 1 units) and the midline is y=o Corn me nt: Corrections: c) What transformations occurred? Stretch/shrink. reection. translation. etc. Please rework d) & e) neatly showing your algebraic steps for nding both the x & y values of the 5 key points. Your graph show be more accurately drawn with the updated coordinates
