Okay, tomorrow I have to study. Like, a lot.

(Will someone please explain piecewise functions to me? Why do I find this so confusing?)

But it is utterly futile to attempt studying at 3:30 a.m., so there.

Anyway. I hung out with t_love tonight, and it was awesome. See, we played mini-golf, and we didn't keep score, but I totally lost. Which is not

Hmm. What can I remember about piecewise functions?

They are in pieces. :P
I'm not sure I'm thinking of the right thing. I could go find some old maths notes, but it's late and am going to be soon. When is the test?

I think (and am probably wrong) they are the functions in bits. They aren't continuous (so you can't differentiate them) as there are breaks in the lines you can see in a graph.
The function equation is then broken up into parts. e.g.
f(x) = 2x for 0

[dosidella]

No, that is what they are.

And, okay, I understand how to find function values with them. Like, in your example, f(1) = 2; f(10) = 4; f(-5) is undefined; etc.

And, basically, I understand how to graph them. Which is really just graphing each equation seperately and combining them, right?

Like, again for this example, the graph would be an open point at the origin, an increasing straight line until (2, 4), an open point at (2, 4), and then a horizontal line going from (2, 4) to positive infinity. And (2, 4) isn't actually on the graph (?).

Um, is that right?

The test is tomorrow (Monday). Eep.

[tenik]

Um, is that right?

Sounds right to me. Yep (2,4) is undefined. Why? because I can't type less than or equal to signs. :P

It's seems like you know this stuff. You'll do fine!

Piecewise functions are really really really confusing. I hate all that graphing stuff. Especially conic sections. *shudder* Eeggghhh.

[dosidella]

Oh, conic sections, conic sections, conic sections. *cringe*

Yeah, I'm completely confused.

(But there are no conic sections on this exam, so hey, silver lining!)

Dude, I KNOW! I was like, "That is the most amazing thing in the world."

what a coincidence...last nite driving around w/ my friend and 2 random guys, we came across a 24 hour mcdonald's..cuz bruce was like "you girls want some mcdonald's?" and im like "umm ur drunk, their closed" and he's like "nooo, they are 24 hours!" and im like "damn, who woulda thought" Where was ur 24 hour mcdonald's at? and i had something else to say, but i forgot.

[dosidella]

Was in Monroeville.

(Is that the same as yours? Because it would ridiculously awesome if there were two.)

[angeleyes04]

maybe..i dunno..i was so tired last nite...and was uncomfortable in the car w/ bruce that i was too worried about gettin to my car...i think it was off of the camp horne rd. exit?

[dosidella]

I...actually have no idea. Heh. But I bet it was, because, seriously, how many 24-hour McDonald'ses could there be?

And speaking of Bruce, I meant to comment on your entry -- that is so messed up. Oh man.
