Let f(x)=12−2x (a) Sketch the region R under the graph of f on the interval 10,6 . 6 Find its exact ares (in square units) using geometry. square units (b) Wye a Riemasn sum with five subintervais of equal iengeh (h=5) to aporoximate the area (in souare unins) ef R. Choose the representative points to be the right encpoints of the subintervals. squsre units (c) Repest part (b) with ten subintervals of equal length (n=10). square units (d) Compare the approximations obtained in parts (b) and (c) with the exact area found in part (a), Do the approximations improve wath larper n? Yes Ns
