In this assessment, students work through scenarios of changing the function rule of the sine and cosine functions by addition and/or multiplication and see how such changes affects their graph. Students explore vertical/horizontal translation, reflection over the x-axis, and vertical/horizontal dilation. As they explore, students use their GDCs to graph functions, describe findings, suggest rules, and verify and justify their results.
