www.sydney.edu.au1.3 The absolute value function Before we define the absolute value function we will review the definition of the absolute value of a number. The Absolute value of a number x is written |x| and is defined as |x| = x if x ≥ 0or|x| = −x if x<0. That is, |4| = 4 since 4 is positive, but |−2| = 2 since −2 is negative.
