Clowns and Graphing Rational Functions

I thought I had heard every silly mnemonic device for remembering mathematical formulas, but I recently heard a new one: the clowns BOBO, BOTU, and BETC for remembering how to graph rational functions.

  • BOB0: bigger (exponent) on bottom, x = 0
  • BOTU: bigger on top, undefined
  • BETC: bottom equals top eponent, coefficients (i.e., the ratio of coefficients)
