Can anyone explain absolute values to me. The definition my teacher gave was a bit confusing x=x if x is greater than or equal to and x= x if x is less than zero. I thought absolute value was just the distance x was from zero so it couldn't end up negative.

x is also known as absolute value of x or modulus x

Now modulus x is a function that is always positive, that is it is always greater than zero.. \[\left x \right > 0\]

so for a positive function the function doesnt change. Let us take an example.. Say x=5 so 5 = 5

Now for a negative function, the function just changes the sign, that is negative sign becomes positive

For eg. we have x= 5 5 = 5

Now if you see the graph of x looks likedw:1326414074983:dw

for modulus x the function looks like dw:1326414124726:dw

As it is always positive

I would like to add that the statement x = x when x < 0 means that for example: Lets say x = 2 so it's less than zero. 2 = (2) Absolute value of 2 is the opposite of 2 which is 2

We have given the user a complete research on modulus... Hope it helps :)

I enjoyed your explanation =) I've seen the confusion with the x = x before (Which should be read as absolute value of x is the opposite of x)
