So without watching the video I immediately draw the constant offset of 3 and start oscillating a cosine function around it. The cosine is scale 5 times so it’s going to oscillate between-2 to +8, then you have to add constant 6 horizontal offset (phase) and scale (horizontal shrink) 2 times, i.e. double the frequency. So now let me watch the video and find out where was I wrong 😂
Hmmm . . . forgot. I wonder . . . well I learned it once and 4.0 the class. That how I would do it. Nah good enough anything too much more we using Computers on.
Student asked me what's the transformations - ruclips.net/video/EQc9u_xBIVA/видео.html
I’ve been watching your videos since sophomore year in high school and now I’m an engineering major! Thank you for the awesome explanations!!

greetings from turkey 🎉 thanks
hey thank you so much you helped my algebra grade go from a 60 to a 89
boom great job!!
What is inside the function is a the period. (2x + 6)/2pi
