Question

The integral of the function $e^x$ is

• A. $\ln |x|+C$
• B. $e^x+C$
• C. $x+C$
• D. $x^e+C$

Answer 1

The correct option is B $e^x+C$

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 $e^x(or{e}^x+c)$.
