About this resource

PowerPoint presentation, 10 slides explaining how to describe three kinds of discontinuities:  Removable discontinuities, Infinite discontinuities and jump discontinuities

In the classroom

Teaching tips & learning objectives

Learning objectives

  • Classify a discontinuity as removable, jump or infinite using f(a) and one-sided limits

  • Determine the intervals on which a rational function is continuous

Teaching tips

  • Each example shows its full solution, so you could pause before the solution step and have students predict the classification first.

Skills covered

  • Evaluating one-sided limits — worked examples compare left and right limits at a point to decide the type of break
