Answer 2

The domain of a function represents all the possible input values (x-values) for which the function is defined. In this case, the function is $f(x) = x^3 + 3x^2 - 1$.

Since polynomials are defined for all real numbers, the domain of the given function $f(x)$ is also all real numbers, which means there are no restrictions on the values that $x$ can take. In interval notation, we can express the domain as $(-∞, ∞)$.
