Math Problem....HELP!?!?!?!

[SkinsMaster88]

Ok, here's some help.

f(x) = a(x-h)^2 + k Where (h,k) is the vertex.

Easy.

Just take your y-intercept coordinate you're given: (0, -6)

x = 0
f(x) = -6

Plug it in.

-6 = a(0-3)^2 + 3
-6 = a(9) + 3
9a = -9
a = -1

Then expand equation.

f(x) = (-1)(x-3)^2 + 3
f(x) = (-1)(x^2 - 6x + 9) + 3

f(x) = -x^2 + 6x - 6

I get 1/3 credit for telling you that c is -6

Man I wish the problem sets I get were this easy. Everything does seem easier than 'rocket science', especially at one of the toughest colleges in the country. Try combining differential equations, triple integrals, eigenvalues, and physics equilibrium equations in problems taking over 2-3 pages per each part.

I hate the 6-8 hr problem sets I have to do.

I like Differential Equations. Easily one of my favorite classes. But it helps to have a really good professor.

Diff Eq is fine. It's just a matter of some time-consuming problems afterwards in engineering.

And THAT'S why I switched to Computer Science.

Man, if you have a good DE professor your math life will always be a thousand times easier. Plus its really hard to find a good textbook. Mine was excellent and I took that class in the summer at a JC. Its made my engineering life so much easier.

And THAT'S why I switched to Computer Science.

Computer science is the DEBIL! Hours and hours of debugging for a mistake you'll never find.

Though I've been told that I need much more software experience in todays job market. Bleh.

Where do you go to school and what are you studying? Triple integrals were kind of annoying especially when you have to think in freaking 4 dimensions. They are even more annoying when trying to set up a probability problem

I got to the party late and missed all of the fun.

What turned me away from engineering was HORRIBLE Physics teachers. My god, I couldn't stand mine. And the fact that my Digital Circuits Prof was a complete ***** didn't help either.

I much prefer CS though. For some reason it just fits my mind better.

Nice. I have a really good friend who goes to GT. I hear its intense

My Physics teachers have all been very good. Its a fun subject.

I'll admit the majority of EE profs aren't great. (that I've had anyway) Mainly, you learn by doing it yourself, and by your peers.

I have 2 that I can hardly understand. I mean literally, they are very difficult to understand. Listening to one of them go though 00 01 10 11 is painful.

It's all jeero's and vone's with me. Atleast I can understand an Indian accent.

You da man!!

Alright, this is for your eyes, and your eyes only. It's making it's ES debut.

If you like me, you better put a ring on me.

No one else watch this.
