Identifying compression and stretching of multiple functions

[@ejejejejejej2162]

This actually taught me more in 3 minutes than my teacher did in 45

[@unsureinlife6240]

I’m actually using you a lot for my hw

[@cailansadeghi2355]

My teacher is terrible

[@isabellasinterlude]

Mine isn’t even present, we’re just watching recorded videos..which isn’t helpful

[@Kayla-of5cz]

@@isabellasinterlude we have to read EVERYTHING. There’s no videos or anything. We’re basically on our own.

This hurts my head oh no so many things to remember

[@ericswisher4187]

I've recently had surgery and have had to do home bound, and all my teachers does is write down the notes give them to me and then he expects me to know it automatically thanks for the help.

[@sleeping85]

Thank you I’ve had Covid and been so confused on my homework. I’ve been crying for 15 minutes

[@goc0707z]

aaaa thank you so much you helped me a lot!!

I just learned more from this 6 min vid compared to my algebra teacher teaching me for 1/2 a year

Yep

when you graph these transformations the visible difference seems to use the opposite term of the actual effect it has. when y=x^2 gets skinnier, they call it a stretch.... when it gets wider its called compression.... nonsense.

[@rosecah]

I try to think of it as grabbing one end and stretching it away from the x or y axis. And for compression I think of it as squishing it towards the x or y axis.

[@Mks_0005]

What you're saying is technically true.. horizontally. When it gets skinner its a horizontal compression (or vertical stretch) and when it gets wider its a horizontal compression (or vertical stretch). The difference kinda makes no sense in quadratics but if you try applying all 4 with, say, a sin function (f(x)=sinx), it becomes so much clearer and you see all the distinctions. Try it on desmos.
