Explanation

Discontinuities occur where f(x) is not continuous:

  1. Jump: sudden change in value

  2. Infinite: vertical asymptote

  3. Removable: hole in graph

Quiz

  1. Name 3 types of discontinuities

  2. What is a removable discontinuity?

  3. What is a jump discontinuity?

  4. What is an infinite discontinuity?

  5. Can a function have multiple discontinuities?

Answer Key

  1. Jump, infinite, removable

  2. Hole in the graph

  3. Sudden jump in value

  4. Vertical asymptote

  5. Yes
