  1. Section 7.1 Rational Functions Cheat Sheet

  2. Parent Function:______________________ The parameters d:__________ e: __________ f: __________ must have don’t need don’t need

  3. Must have at least 4 points on each side of the vertical asymptote Points for the function:_____________________________ Vertical Asymptote:______________ Horizontal Asymptote:___________ There is always a vertical and horizontal asymptote.

  4. Range: ________________ Domain: ________________ Y-intercept:_______________________________ Set x=0 and solve. If there is no e, then there is no y-intercept

  5. This is the same thing as an x-intercept. You can use the trace feature on your calc to approximate Find the Zero(s):________________________________ Increasing or Decreasing:____________________________ Set y=0 and solve. You will have to cross multiply to solve for x. If there is no parameter f, there is no zero. The function is either Increasing or Decreasing. It can’t be both
