I Have A Gay Ass Diploma

anyone?

[Pearl Jam]

what up pj

hey dude

[Fit of Rage]

anyone?

I thought he was making enough of an ass out of himself that it would have been overkill. But ok, you went there.

D1st0rt, what math are you taking, differential equations or numerical analysis?

I could've taken Diff EQ this semester but decided not to since I'm already in Multivariable

[Verthanthi]

whatever, i just proved p = np.

[DoTheFandango]

n=1 or n=0.

i win.

For some reason I thought multivariable (calc 4 for me) was easier than calc 2 (integration techniques). No idea why.

You have some reading to do

[DoTheFandango]

I know the whole thing, I just like making jokes of the whole "hardest problem in the universe" thing.

I BET U PPL ARE TOO DUMB TO SOLVE THESE!

|parent function|     |transformation|  

f(x)=x                    f(x)=x-4

f(x)=1/x                 f(x)=1/x+4
 
f(x)=|x|                 f(x)=|x-3|

post answers for me to check

first one, -5
second one, i'll assume you mean 1 / (x+4) and not (1/x)+4 .. in the first case, the answer is 1/4
third one, 2

and d1st0rt, i'm only in calc II right now.. you have me beat. :9

These are very simple linear/quadratic functions
the first one is a linear equation, which is simply y=ax+b, b is the y-intercept
the second one is a reciprocal function, which is y=a/(x-h)+k. The asymptote is moved right/ left by h value, up or down by k
The third one is an absolute value, it can be written as y=a|x-h|+k, h is vertex to the right, k, up.

but for this overly ez question, just plug in the values. For ex the first one would be

f(x)=-1-4=-5
f(x)=0-4=-4
f(x)=1-4=-3

These questions are for intelligent ppl? thats just sad...wtf
This is grade 7 stuff, i assume?

second one, i'll assume you mean 1 / (x+4) and not (1/x)+4

Thats wrong, they are too totally different values that control the dif components in terms of graphing (x,y transformation)
when x=1 for example,
1 / (x+4)=1/5 (not 1/4 anyways)
(1/x)+4=5

He never said they were the same...
