Question

Which of the following is the integral of the function $e^x$

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

By integrating $e^x$, we are trying to guess some function whose derivative is $e^x$. We know that derivative of $e^x$ is $e^x$it self. So the integral of $e^x$should also be $e^x(or{e}^x+c)$.This is one of the standard results we are supposed to remember to solve questions.
