Which is an antiderivative of \(f(x)=x e^{x^{2}}\)?

Choose one option.

Show answer
  • D. \(\frac{e^{x^{2}}}{2} + C\)

Explanation

By the chain rule, \(\left(\frac{e^{x^{2}}}{2}\right)'=x e^{x^{2}}\). The other options have a different derivative.

Review the concept: Antiderivative

An antiderivative of \(f\) is a function \(F\) such that \(F^{\prime}=f\). If \(F\) is an antiderivative of \(f\), all the others on an interval differ from \(F\) by a constant.

\[F'(x)=f(x)\]
