Let f (x)=/x for 1<x <7.Use a Riemann sum withn=6 subintervals and sample points the midpoints of the intervals to estimate the area A between the graph of f and the x-axis. The answer that best describes the estimate is
a. A=13.478
b.A=15.306
c.A=11.680
d.A =11.693
E.None of the other choices is the required Riemann sum
