(4 points) Evaluate the indefinite integral fav 8 + x4dx by making a u-substitution. U= (Give a function of x here.) du = When you make the substitution, the integral becomes k f g(u) du where g(u) = (Give a function of u here.) K = (Give the constant that would be needed outside the integral.) Now do the antidifferentiation. k S g(u) du = (Don't forget the +C. "C" must be capital not lowercase. ) Give the final result by substituting the function of x back in. fav8 + x'dx =
