Algebra I: Calculating absolute value
This is a free lesson from our course in Algebra I
This lesson explains how to find the absolute value of a function. It has several examples that will help you understand the concept of absolute value of functions. the absolute value of x, denoted "| x |" (and which is read as "the absolute value of x"), is the distance of x from zero. This is why absolute value is never negative; absolute value only asks "how far?", not "in which direction?". This means not only that | 3 | = 3, because 3 is three units to the right of zero, but also that | –3 | = 3, because –3 is three units to the left of zero. Overall, the mathematical formula for absolute value is:
               |x| = x, if >= 0
               |x| = -x, if x < 0
