Linear Equations and Inequalities

Absolute Value Functions - Example 3

In mathematics, the absolute value or modulus |x| of a real number "x" is the non-negative value of "x" without regard to its sign. That is, if "x" > 0, then |x| = x; if "x" = 0, then |x| = 0; and if "x" < 0, then |x| = ?x. The absolute value of a real number is also known as its magnitude. The absolute value of a complex number z = x + iy is x^2 + y^2, where x^2 + y^2 = |x + iy| = x^2 + y^2 = |z|.
