Thread: Domain Rule

If I am trying to calcuate the domain. There is an absolute value, so would I set the part inside the absolute value brackets to: greater than or equal to zero, greater than zero, or not equal to zero. Thanks for the help.

Perhaps it would help if you posted the function...

I just looking for a general rule...

denominator: =/ (not equal to zero)
square root: >= (greater than = to)
log:> (greater than)
absolute value: ?

Then consider the archetype:


This function is defined on all real numbers, so the domain is . The basic idea is that there is a y value for every real x value.
