Practice On Your Own 1. Estimate the area under the curve f(x) = 10 -3x on the interval [0, 2] using n sub-intervals of equal width and right endpoints. Your final answer should include only numbers, arithmetic operations, trigonometric and/or logarithmic functions, and the variable n.2. Use the previous problem to express the exact area under the curve f(x) = 10 -3.x on the interval 0, 2] as a limit of finite sums. Your final answer should include a limit and can also include numbers, arithmetic operations, trigono- metric and or logarithmic functions, and the variable n. 3. Evaluate the limit from the previous problem to determine the exact area under the curve f(x) = 10 -3x on the interval [0, 2]. (Hint: The correct final answer is 14.)
