For Math Elitests

[Money]

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|



____x______y____
     -1  |   ?
      0  |   ?
      1  |   ?

post answers for me to check

Ten bucks says you looked these up before you posted them, and that you couldn't solve them yourself if the question was posed.

In other news, AFK while I solve them.
EDIT:
Wait, is it 1/x+4 or 1/(x+4).

Big difference.

this sure is an eliTEST

im working on em, wanted to test my math skillzzzzzz, been a while since school wanted to see if i remembered anything

first one to do it gets 10 e-dollars

Wait, is it 1/x+4 or 1/(x+4).

Big difference.

its exactly like i wrote it!

[DoTheFandango]

y=4
y=3
y=4

i think. If I read this right, I just move right to left, then down again.

x = x-4.0;
x = 1.0/x;
x = 1.0/x+4;
x = Math.abs(x);
x = Math.abs(x+3.0);
return x;

haha, there's your elitism.

THere is no way I'm doing someone else's math hw.

Wow Money, are you actually going to try to complete pre-Algebra for you GED?

[Sleepy Weasel]

are you just asking for the y value after you take those basic graphs and transform them, given the x values? Cause that's like.... really really easy? Or am I wrong here? This is your math homework or something? Seriously you can't just plug in the x value and figure it out?

Im Not In School

[Money]

And I Have A Gay Ass Diploma I Dont Need A Ged Lol

i dont know algebra im helping my wife with her homework my head hurts from thinking she knows the shit but has me doing it,,

[Sleepy Weasel]

You just put the x value in for x. I don't know what DTF is trying to do... but


x-4. And you say x is -1. so -1-4. That's -5.

1/x+4. x is 0. Well you can't divide by 0... 1/x at 0 asymptotes to infinity and then you shift it up 4, so it's infinity. Of course it asymptotes to -infinity from the left and +infinity from the right.. so maybe they want undefined, I don't know what they want.

If it's 1/(x+4) then it's 1/(0+4) or 1/4 or 0.25

|x-3| x is 1. |1-3| -> |-2| -> 2

there you're done.


These seem like questions where they would ask you to draw the basic graph of the function than draw the transformation (shift the graph up/down/right/left) as they are all basic f(x) equations with a little shift to them. I think that's what they're trying to teach. But if they give you x and they want f(x)... just put in the value for x and get f(x).


Or maybe they want the value at -1,0,1 for all of them? So

f(x) = x -1 : -5,-4,-3
f(x) = 1/x+4 : 3,undefined,5
f(x) = |x-3| : 4,3,2

these are dumb and it amuses me that sleepy weasel wasted any amount of time thinking about them

[Kim]

Haha sleepy =p

ownt

[Blood]

that's like elementary
