Match the graphs with the formulas. Formulas are given in order A, B, C. Graphs are numbered 1, 2, 3.

Solution:

• Formula A) $$y = \frac{2}{x}$$ corresponds to graph 2. This is a hyperbola in the first and third quadrants.
• Formula B) $$y = \frac{1}{2x}$$ corresponds to graph 1. This is also a hyperbola, but with a narrower spread than graph 2.
• Formula C) $$y = -\frac{1}{2x}$$ corresponds to graph 3. This is a hyperbola in the second and fourth quadrants.
