Question

Is there a particular term for the expression within absolute value bars?

Like: the expression under a radical is the 'radicand,' the expression under the long division symbol is the 'dividend,' and so on.

Anyone want to propose a term? What shall we call the (2x+1) in |2x+1|?

The 'absolund?'

Answer 1

g(x) :)

Answer 2

I was talking about solving absolute value inequalities with a student yesterday and had to say things like "if what's inside the absolute value bars is negative..." and "here, set the expression inside the absolute value equal to zero" - and I wondered if there's a way I could shorten that up to maybe, "What if the absolund is a negative number?"

It would be so much quicker to say!

If there is no official term, I'll just go ahead and coin the above and see if it catches on.

Answer 3

argument seems appropriate

Answer 4

would "modulus" define the innards? or the whole |..| ?

Answer 5

'modulus' is the result of taking abs.val.
It's my understanding that 'absolute value,' 'modulus,' and 'magnitude' are pretty much synonymous.

|x| is the modulus of x.

'Argument' is good enough for me for now, but it's still generic. The innards of any function is the argument. I was hoping for something like 'radicand' that applied specifically to absolute value.

Answer 6

absolutand.... duh... :)

Answer 7

^ Good suggestion. Thank you.
