Graphing Reciprocal Functions Using the Big/Little Concept

Concept

-> numbers getting larger
-> numbers getting smaller
-> numbers getting smaller
-> numbers getting larger

Steps for Graphing

1. When , it's reciprocal is also 1 (since is )
   • Same with
   • All points on the graph with are part of the reciprocal
2. The y-int of the reciprocal is the reciprocal of the y-int of the original function
3. Get asymptotes
   • Vertical asymptotes exist for the reciprocal function when the original function as x-intercepts
   • Calculate horizontal asymptote with Rational Functions
4. Use big/little concept
