Discussion-Based Assessment Assigned Problems 1. Evaluate the Riemann sum for (x) = x3 - 6x, for 0 s x 5 3 with six subintervals, taking the sample points, xi, to be the right endpoint of each interval. Give three decimal places in your answer. 2. Explain, using a graph of f(x), what the Riemann sum in Question #1 represents. 3. Express the given integral as the limit of a Riemann sum but do not evaluate: (x] -6x)dx . 4. Use the Fundamental Theorem to evaluate (x3 -6x)dx. (Your answer must include the antiderivative.) 5. Use a graph of the function to explain the geometric meaning of the value of the integral. Print
