I'll provide my opinion on the desmos table: I quite like it because if you get the hang of it I think it will ease students' anxiety more because you can have three points of a quadratic and instantly get the quadratic, you can also have very few points on a line and get the equation immediately in the format you want (getting rid of point slope if you don't like to do that) it has so many use cases, although it "may" take just a tiny bit more time, I think people will enjoy the fact that they didn't have to use their brain. :)
For the question: f(x) = 4x^2+64x+262 The function g is defined by g(x) = f(x+5). For what value of x does g(x) reach its minimum? You can type in the original line in desmos for simplicity: f(x) = 4x^2+64x+262 and then literally type in f(x+5) That will save you time from inputting the "x+5" for every single instance where x is in the equation. This will literally give you the new function for the problem (g(x)) and you can see the minimum easily as you were. As you were.
5:22 i had a question. I saw that the second equation, y=2x was created from the problem as b=2r. But b and r are the amount of miles that she ran an biked. But you put y=2x for time when the problem says "twice as many hours." wouldn't it be y=4x?
Great question! I should have been clearer-my x and y represent hours, not miles. The equation y = 2x reflects ‘twice as many hours,’ and 5x + 10y = 200 comes from the total distance equation, based on their speeds. Thanks for pointing that out!
I won't be doing a dedicated video for those before the December exam, but I could perhaps include them in my predictions video (since i do predict we'll be seeing them 🤓).
For your DESMOS cheat sheet shortcuts, using abs() for absolute value seems like a cool option too because you don't have to type the complex character that looks like an I or a lower case l | Can you tell the difference between the three? Il|
hi i was downloading the cheat sheat but it's showing the owner of this website has banned you from downloading the cheat sheat plus i have my SAT day after tommorow could u please reply fast please
As a Jamaican trying to ace the SAT without being taught the curriculum, blessings 🤝
Blessings to you, and good luck!

Agreed. There's only so much brain to go around when you're forced to take an exam for two and a half hours.

You can type in the original line in desmos for simplicity:

As you were.
That's a great approach-thanks for sharing!
Damn! Finally!!
Please also make a vid on shortcuts!
I can do that. Did you download the cheat sheet?
@@TestPrepDad i tried to, it shows an error whenever i put my gmail
@@fanstargaming6585 Weird. I just tested it, and it seems to be working fine. What's the error?
for the single variable equations 28:26 do both usually have to be y form and only the value is x?
If I understand you, then yes. You will want to set both equal to Y, and the only real value you worry about will be x (hence, "single" variable).

please make trig and circle problems review

On a standard keyboard it's just "shift" + "\". I will add the alternative to the cheat sheet though.
Life when the constant values don't exist on the Sat :😍🥰🤪🧠🌈
😄
Lol that mouse meme 😂

😢 finally

That's incredibly odd. Send me an email, and I will see what I can do: robertteachesenglishyt@gmail.com
