College Algebra

Definition

An endpoint is a point at one end of a segment or the starting point of a ray. It represents the limit or boundary of a function on a given interval.

congrats on reading the definition of endpoint. now let's actually learn it.

ok, let's learn stuff

5 Must Know Facts For Your Next Test

  1. Endpoints are critical in determining the domain and range of functions.
  2. In intervals, endpoints can be either included (closed interval) or excluded (open interval).
  3. Endpoints are used to define the behavior of graphs at their boundaries, including limits and continuity.
  4. When calculating rates of change, endpoints help in identifying specific intervals over which changes occur.
  5. Endpoints often indicate where the function starts and stops increasing or decreasing.

Review Questions

  • What role do endpoints play in defining the domain and range of a function?
  • How do you distinguish between open and closed intervals using endpoints?
  • Why are endpoints important when analyzing rates of change in functions?
