Review the graph. On a coordinate plane, a sine curve has a maximum of 3 and minimum of negative 3. It completes one period at pi. Which statement about the graph is true? the period of the graph is startfraction 2 pi over 3 endfraction the amplitude of the graph is 2 units. The domain of the graph is from –3 to 3 and is inclusive. The graph represents a reflection over the x-axis of the function y = 3sin(2x).
