question 1

A continuouslydecreasing function that is concave down on the interval [3, T] is represented by the table. x} 1.946 1.705 1.609 1.361 1.099 Part A: Find the left Reimann sum estimate of I: {(1)113- based on the subintervals given in the table. (4 points} Part B: wnte the midpoint Reimann sum that estimates I: mom. based on the subintervals given in the table. (4 points) Part C: Determine whether the left Reimann sum estimate is an overestimate or an underestimate. based on the properties of the function. (2 points) The graph of the function f on the interval 0 s x s 9 consists of three line segments and the point (4, '4). as shown. It is given that 9005\" = _a and 1999009\" :12 Part A: Find the value of j:'(x)'. or explain why the integral does not exist. (3 points) Part E: Find the value of Hxldt- Show the work that leads to your answer. (3 points} Part 0: Find the value of Eng\"). :0de Show the work that leads to your answer. (4 points)
