This is in the CPM precal book, chapter 4, 4-133, 4-134 and 4-135. Mostly just try and solve 4-135 please.

Change Y3 to 13 = sin(A) + 2cos(X). On the resource page, sketch the graph and label # h(x) = sinx +2cosx. How is h(x) the same as g(x)? How is it different? 4-135. Change Y3 to 13 = sin(A) + cos(2X). Sketch the graph on the resource page and label 4-134. # k(x) = sin x + cos(2x) . How is this graph the same as g(x)? How is it different? what if we add a periodic function with a linear equation? Using the Lesson 4.3.2B 4-135. Resource Page, use graphical addition to find the graph of y = x + sinx. Describe the graph
