# Graphing Hyperbolas

 Hyperbolas Simple Hyperbola, in the form y = A/x and y = A/Bx Graph asymptotes, shape and features (symmetry) Remember to define the Domain if you write the equation for part of a Hyperbola graph. AND define the 'x' value not defined for the vertical asymptote eg x ≠3 Hyperbola Graphs Class notes, Blank notes | Daves notes | Worksheet Ex11.01 Hyperbola p45, GeoGebra Java Hyperbola Translated Hyperbola Sketching hyperbolas in the form y = A/(x+B) + C Finding both intercepts, asymptotes & sketching translated hyperbola  Ex11.02, Ex11.03 p46, p47
