What is the antiderivative of $3x^2$?

$x^3 + C$

What is the antiderivative of $cos(3x)$?

The antiderivative of $cos(3x)$ is $rac{1}{3}sin(3x) + C$, where $C$ is the constant of integration.

Determine the antiderivative of $e^{2x}$.

The antiderivative of $e^{2x}$ is $rac{1}{2}e^{2x} + C$, where $C$ is the constant of integration.

What is the antiderivative of $f(x)$?
