27 problems · 20-25 minutes · Skills: continuity, calculus, functions

About This Worksheet

This hard-level worksheet contains 27 problems designed for 12th Grade students practicing continuity of functions. Hard worksheets feature challenging problems including multi-step questions, missing values, and real-world applications to push students further.

Continuity is one of the most important properties a function can have — it guarantees that the function behaves predictably and that calculus tools apply. The Intermediate Value Theorem, a consequence of continuity, is a foundational existence theorem used throughout calculus to prove that solutions to equations must exist.

  • State the three conditions for a function to be continuous at a point
  • Classify discontinuities as removable, jump, or infinite
  • Apply the Intermediate Value Theorem to guarantee the existence of roots
  • Determine a constant that makes a piecewise function continuous
  • Identify the type of discontinuity from the limit and function value
