Transformations - Stretches and Relfections of Functions

A 16 minute, 20 second video lesson on how to symbolically and graphically stretch, compress and reflect functions and their graphs vertically and horizontally. For some reason, the audio is about 12 seconds ahead of the video. Also, I misspoke in the recording and described y=f(-x) as a reflection over the x-axis. It's not, it's a reflection over the y-axis. Everything else I described about those sorts of reflections (y=f(-x)) is correct.

@isthatmarcee Glad it helped you. Someday I've got to redo it a little better. Around the 8 min mark the video and audio are out of sync.
