Problem Statement

What is a piecewise function?

Step-by-Step Explanation

A piecewise function uses different formulas on different parts of its domain.

  1. Identify what the question is asking. In Precalculus, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
  2. Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
  3. Work one step at a time and keep units, signs, and restrictions visible.
  4. Check whether the answer makes sense in the original context.

Final Answer

A piecewise function uses different formulas on different parts of its domain. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
