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.

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. :)

Damn! Finally!!
Please also make a vid on shortcuts!

for the single variable equations 28:26 do both usually have to be y form and only the value is x?

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?

please make trig and circle problems review

Life when the constant values don't exist on the Sat :😍🥰🤪🧠🌈

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?
