This GeoGebra example dynamically demonstrates translations and scaling of a hyperbola, showing how parameters a, h, and k affect the graph of y = a/(x-h)+k. Core mathematical concepts include the standard equation of a hyperbola, asymptotes, horizontal/vertical shifts, vertical stretch/compression, and the role of parameters in shaping the curve. Construction highlights: using sliders or input boxes for parameters a, h, k, the function command to plot the hyperbola, and possibly auxiliary objects like pic1, constant c, and b to mark key points or asymptotes. Suitable for high school or early college students learning function transformations and coordinate geometry, and for teachers as an interactive demonstration to visualize parameter-image relationships.
