One-Sided Limits Worksheets

Evaluate limits with the approach direction stated and distinguish limits from function values.

Before you begin

Manipulate algebraic expressions and understand functions, limits and derivative notation.

Worked example

f(x) = 7 when x < 4, and f(x) = 11 when x ≥ 4. Find the limit as x approaches 4 from the left.

  1. Use the branch on the requested side of the boundary.
  2. A one-sided limit need not equal the limit from the other side.
