How to Graph Reciprocal Function y = 1/f(x)

#reciprocalfunction #graphingfunctions #hscmathematics In this video tutorial, we explain using example on how to sketch the reciprocal function y = 1/f(x) when given the graph of y = f(x). We follow the checklist of features on f(x) 1. f(x) = 0 2. f(x) approaches 0 3. f(x) approaches infinity 4. f(x) = 1 or -1 5. y-intercept of f(x) 6. turning point of f(x) This is part of NSW HSC Extension 1 Mathematics course – Graphing Techniques
