Graphing Cosine with Reflection and Change in Period

👉 Learn how to graph a cosine function. To graph a cosine function, we first determine the amplitude (the maximum point on the graph), the period (the distance/time for a complete oscillation), the phase shift (the horizontal shift from the parent function), the vertical shift (the vertical shift from the parent function) and the x-scale (the distance between the turns and the x-intercepts). After we have obtained these features, we plot the points on the graph and graph accordingly.

sweet, happy to help, I have a whole playlist on these graphing videos

This was so awesome! I got the concept of the transformations, but I was struggling with the actual graphing. My teacher didn't teach me how to find the critical points, just to "change my scale" which I didn't know how to do.
Thanks so much! I think I can actually graph now!
