Problem $2$: $(6$ points$)$ Suppose you know that $G(x)$ is an antiderivative of $g(x).$ Evaluate the following integrals in terms of the function $G$ or state that there is not enough information.

$(a){\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}g(x^3)dx,$

$($b$){\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}g(4-3x)dx$

$(c){\displaystyle \underset{\phantom{}}{\overset{\phantom{}}{}}}4x*g(x^2)dx$
