Simpson’s rule assumes the function to be ___________(a) constant(b)

1.	Simpson’s rule assumes the function to be ___________(a) constant(b) cubic(c) linear(d) quadraticI have been asked this question in unit test.My question is from Finite Volume Methods in chapter Finite Volume Methods of Computational Fluid Dynamics
Answer» The correct answer is (d) quadratic To explain I would say: Simpson’s RULE ASSUMES the FUNCTION to be integrated as a quadratic function. The points chosen to generate the quadratic LINE are the two endpoints and the midpoint. So, this APPROXIMATION is more accurate.
