Question: 1 / 400

What does the absolute value |x| represent?

The negative of x

The distance of x from 0

The absolute value |x| represents the distance of x from 0 on a number line, regardless of direction. This means that whether x is a positive or negative number, the absolute value will always yield a non-negative outcome. For example, if x is 3, the absolute value |3| equals 3, and if x is -3, then |−3| also equals 3. This concept is fundamental in mathematics as it allows us to describe quantities in a uniform manner, focusing on magnitude rather than direction. This understanding is crucial in various mathematical applications, including solving equations and inequalities where only the size of a number matters, not its sign.
