Question 1

The following table gives values of an unknown function  f(x)  determined by experimental measurement. Find the best  Midpoint Rule approximation you can for dx based on the values given in the table.

xf(x)
2.001.052
2.251.042
2.501.034
2.751.026
3.001.020
3.251.016
3.501.012
3.751.010
4.001.008

◦ M4  =  2.0460
◦ M4  =  2.0470
◦ M4  =  2.0465
◦ M4  =  2.0480
◦ M4  =  2.0475

Question 2

Given that  f"(t) < 0  on the interval  [a, b],  what can be said about  the relationship between the values of  the integral   I  = dx,  the Trapezoid Rule approximation  Tn  for  I, and the Midpoint Rule approximation  Mn  for  I?
◦ I  <  Mn  <  Tn
◦ Mn <  I  <  Tn
◦ Tn <  Mn <  I
◦ Tn <  I  <  Mn
◦ It is impossible to tell.
