Evaluating piecewise functions

Choose the rule whose condition includes the requested input.

  • Check the input against the inequalities before substituting.
  • At a boundary, the equality sign tells you which rule includes that value.
  • Use exactly one rule for each input.

Example 1

Below the boundary

Evaluate the piecewise function at the stated input.
