Find the indefinite integral. Remember to include a \"+ C" if appropriate. Enclose arguments of functions in parentheses. For example, sin (23:). 1 [(m W) m 1 (a) Estimate the area under the graph of the function f (at) = from a: = 0 to a: = 3 using a Riemann sum with n = 10 subintervals and right z+3 endpoints. Round your answer to four decimal places. 1 (b) Estimate the area under the graph of the function f (z) = from a: = 0 to a: = 3 using a Riemann sum with n = 10 subintervals and left 3+3 endpoints. Round your answer to four decimal places. area = Number Estimate the area under the graph of the function f (x) = vac + 3 from a = -1 to a = 5 using a Riemann sum with n = 10 subintervals and midpoints. Round your answer to four decimal places. area = Number
