First of all, according to | y | = 1 / x, 1 / X & gt; 0, so the domain of definition is (0, ∞). So we should draw an image of y = 1 / x, X ∈ (0, ∞), as shown in Figure 1. Because y has an absolute value, we should also add an image of - y = 1 / x, X ∈ (0, ∞), so we should draw Figure 2 according to the x-axis symmetry of the image of Figure 1
