The graph of f(x) = 4x-x over [1,4] is provided. It is known that the area under the curve is 9. Use the right-point method and left-point method to approximate the area under the curve via the Riemann sum. The number of subintervals for each method is n=4. Draw the boxes on the provided plot for each method. Also, compute the errors. Which method yields a more accurate result? The graph of f(x) = 4x-x over [1,4] is provided.
