The notation $\int 2x \, dx$ is a compact way to ask for the antiderivative of $2x$ with respect to $x$. It represents the entire family of functions whose derivative is $2x$, which is written as $x^2+C$.

Conditions: The variable of integration is $x$.; The integrand is $2x$.

The indefinite integral of $2x$ is $x^2+C$. In this context, the term 'indefinite integral' is simply another name for the antiderivative, representing the family of all functions whose derivative is $2x$.

Conditions: The expression being integrated is $2x$.; The result includes an arbitrary constant $C$.

The indefinite integral is simply another name for the antiderivative. Both terms refer to the family of functions whose derivative is the given function, typically expressed with an arbitrary constant $C$.

Conditions: The context is introductory calculus focusing on reverse differentiation.; The function is continuous or differentiable on the interval of interest.

The general form of the antiderivative of $2x$ is $x^2+C$, where $C$ represents an arbitrary constant. This is because multiple functions differing only by a constant share the same derivative.
