True or false: every continuous function has an antiderivative expressible in elementary terms.

  • A.True, the fundamental theorem guaranteeing it
  • B.True, provided the function is also bounded
  • C.True, whenever the interval of definition is closed
  • D.False, an antiderivative existing but not always in elementary form

Answer: D

The fundamental theorem guarantees that \( \int_{a}^{x} f(t)\,dt \) is an antiderivative of a continuous \( f \), so one always exists. Whether it can be written with the elementary functions is a separate question, and \( e^{-x^{2}} \) is the standard case where it cannot
