    Key Skills

    Absolute value
    AHL 2.16

    The absolute value of x is defined as

    {∣x∣=​
    Solving inequalities of functions
    AHL 2.15

    Inequalities of the form

    g(x)≥f(x)

    can be solved either algebraically or with technology.


    It is crucial to remember that when multiplying both sides of an inequality by a negative number, the inequality changes direction:

    −x<1⇒x>−1.
