Exercise · ZW-INTEGRABILITY-OF-CONTINUOUS-FUNCTIONS-003 · ★☆☆ Basic

The integrability theorem for continuous functions requires the domain to be:

Choose one option.

Show answer
  • B. A closed, bounded interval \([a,b]\)

Explanation

A closed, bounded interval is required. On \((0,1)\), for instance, \(1/x\) is continuous but unbounded, and on \([1,\infty)\) the Riemann integral is not defined.

Review the concept: Integrability of continuous functions

Result stating that every function \(f\) continuous on a closed, bounded interval \([a,b]\) is Riemann integrable there.

\[f\text{ continuous on }[a,b]\ \Rightarrow\ \int_a^b f(x)\,dx\text{ exists}\]
