How can the result of an integration by substitution be checked?
AIntegrate the answer a second time
BEvaluate it at the point x = 0
CDifferentiate and compare to integrand
DSet the constant C equal to zero
Answer & Solution
Correct answer: C. Differentiate and compare to integrand
Differentiation undoes integration, so differentiating a correct antiderivative returns the original integrand.
