Absolute Value Function

Absolute Value is when a function equation is expressed within absolute value symbols. For example y = |x|. |x|is mean the absolute value of x. In this example when x = 4 then y will equal 4. But if x = -4 then y will also be 4, this is because absolute value describes the distance from zero that a number is on the number line, only considering the distance. The absolute value of a number will never be negative.
