    Reference: AQA

    For y = a/x and y = a/x², the axes act as vertical and horizontal asymptotes, so the curve approaches but never touches them.
    AQA · B: Algebra and functions (study guide)
    Lines that the curve approaches ever more closely without meeting, drawn as dashed labelled lines, such as x = 0 and y = 0.
    WJEC · Algebra and Functions (AS Unit 1: Pure Mathematics A)
    Tangent is undefined at π/2 + kπ for integer k, and its graph shows asymptotes for tangent.
