This week in PreCalc we learned about reciprocal functions and how to graph them in linear and quadratic functions. Reciprocal functions are very different graphs from absolute value functions and it’s important to notice the difference between them. When graphing reciprocal functions the two most important things are the asymptotes and the invariant points, these will help turn the parent function into the reciprocal function.
