Cramming for a test. Need reminder on how to solve something

[languid bear]

Hi! I took notes on something, but my dumb self forgot to write down the process on how to do it. If anyone knows how to do this stuff, could you remind me? I mainly need to remember how to do “Algebraically” and “Verbally”. Thanks!

Are you allowed a calculator

[languid bear]

Yes

I have a TI 84 graphing calculator

Ok, so we have the T(t)

What are tthe input and output variables

[languid bear]

I’m going to be completely honest with you- I am not sure-. 🥲

I could be missing something here-

I’m sorry, is this unsolvable without this information? If so, I could close the forum and try and figure it out myself 😅

@cedar coral (Just read your bio)

Shoot i stopped checking discord

But anyways, the thing outside the parentheses is the output
the thing inside the parentheses is the input

So in the context of T(t)

• t is the input
• T is the output (it outputs the calculation of -0.38t^2 + 9.4t + 28)

OHHHHH I SEE

So I’d like-
