I need some math help.

X^X

not x+x......

I need a graph of x to the power of x where x is any real number.

well, try using 3/4 and stuff like that or -3/4 and -2/4 and 2/4 and stuff...i get something thats kind of weird. Especially considering some of the fractions are bigger than 1 and some less.

also forgot, with the negatives use it like this -2 would be (-1)(2)^x. Not (-2)^x

You can't split up an exponential.
That's like saying 4^4 = 2*2^4.
So my way is correct, it's the whole of x^x.
Not just positive value of x.

Correct way of splitting
for x = (-2)
y = ((-1)^x)*((2)^x)

no, you see its like this

(-1)(3)= -3
-3^-2 = -1/9
(-3)^-2=1/9

if its not in parentheses it doesn't abide by the rule of signs. Thats why a graphing calculator has -4^2=-16.

Dude
If you have x^x
That means the whole !!!!!!!!! x
Whether x be 3, -2, -4.5 or w/e
You include the negative!!!!
The calculator doesn't, the calculator is stupid.
YOU INCLUDE THE WHOLE X!!! @@@

Dude, i study maths.
Trust me, i'm right.

but your not!

Even my text book says your wrong. So does my calculator and so does my teacher, who was a professor at the airforce academy.

Look, try this problem.

y=-2^x

make x=2

the point (x,y)=(2,-4)



http://www.mathsisfun.com/graph/graph.html used this site tog et the graph, which is the same as my textbooks


p.s-mr death yours looks the closest so far from what Ive tried. Thanks for the visual.

THE Airforce Academy

Its the collage for those going into the Airforce and become officers such as West Point(Army officer) and the Naval Academy(Navy officers).
Its known mainly for its great engineering department and Aero department.
He has a Masters or Doctorates degree, cant remember which.


Yea and what I was doing was the negative x value as an example on how you were wrong. And yes X^X can not be graphed on a calculator, cuz then its wrong, i said that.

Gibble- Its not a parabola, use your calculator and go to table, for my class I have to explain what it does, but i don't know what the main part of the graph looks like, unless Mr. Death was correct which i believe most of it is..And no .5^.5 isn't imaginary. Its a real number.

Yeah, the decimal/fraction thing, I'm thinking of something else, scratch that completely. And I know what you're saying about the negative side.

Yeah, the graph just looks like what Mr. Death posted, simple.

Why would I got to a table on my calculator though? A table is just like a (X,Y) plot rather than a function of Y.


I've taken math through single variable calculus, but I'm still confused on your problem.

A graph of Y=(X)^(X) is just an exponentially increasing curve on the positive side.

HOWEVER

On the negative side the curve approaches the limit of 0, from a negative Y value (third quadrant, I dunno, whatever, you know what I mean).

I'm headed to bed now, if you figure it out tomorrow let us know, or I can figure it out, my math teacher would be happy to explain it.

Is exactly what I said.

However it only works for integers.
Rational numbers would be ugly.

It wouldn't be 1/-9, it would be 1/-27 because you're cubing the three when you bring it to the bottom of the fraction.

You could use a Graphing Calculator, but you'd have to make sure there are parenthesis around everything you want to indicate as a single value. I'm not sure if that would be faster or slower, depending on how long it takes you to get around your calculator.

What re you talking about? Either you made a typo, or just got some things mixed around while you were typing.

-2^-2 = 1/(-2)^2 = 1/4 = 0.25

When you bring the exponent to the denominator, you make it a positive exponent. Since the exponent in this example is 2, it would be a -2 squared, which would ALWAYS be positive.

For -2^2, that is simply 4.
(-2)(-2) = 4

+1

Though, Geometry's kind of fun.

I dont think it works like that.
It will be -1(1/2^2) i think.
I put the -1 there just to show that the whole thing is negative.
Also , on a calculator -2^-2 = -0.25

No.

Ok, well heres some stuff

Maths was correct about it oscillating in the negatives from postives to negatives.(pre Calc teacher thought i said something different and i interpreted it wrong)--Sorry maths I was wrong tbh =(

Now, Everyone is pretty wrong.

Georgio- It is a function, my teacher made that clear when he explained that to us.

Maths- It does more than oscillate in the negative side, my teacher said "This function does something more on the negative side than just oscillate."(Something like that)

P.S-- Only 1 person who had taken his class in the last 20 years has gotten the equation correct in those taking his pre-calc class, and the person who did it aced the sat math section and missed like 5 questions on the English.
If any of you go to college or university or something. Could you ask your professor tbh.....My teacher said it was pretty much so weird its almost incomprehensible so yea idk.

He said that I am way off on what i showed him. Its not deaths graph or what maths explained so yea.....Unless people want to keep trying just don't post because im extrememly confused so uhh yea.

What?

If this is what you're given: 2^-2 and you're asked to simplify you'd follow this procedure:
2^-2 --> 1/2^2 --> 1/4 --> .25

I have no idea where you're getting your figures from.

Put this into the calculator:
(-2)^(-2) you'll get a positive .25.

Goddamn. F your teacher man, , not even gonna explain it for us.

Tell him I want to know

**** , you're right
