Absolute Value Function

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.

Properties

1. There must be at least one point you cant find a slope.

examples of Absolute Value Function

1. f(x)=|x+4|
2. f(x)=|2x|-2
3. f(x)=|x+4|-3
4. f(x)=|x|-3
