Reflections and Graphing Reciprocals

Yesterday we learned about reflections (flips). I wrote everything down but I didn't quite understand what was going on. I will watch the recording tonight and hopefully understand what was taught to us yesterday.

Today we learned about reciprocal functions and how to graph them. We observed that:
1. f(x)'s x-intercept is 1/f(x)'s asymptote.
2. In the same interval (left to right, or right to left) f(x) is "greatering" and 1/f(x) is "lessering" (or vice versa).
3. It seems the at values of y=-1 and y=1, the graphs of f(x) and 1/f(x) are at the same place.
