Estimate the area of the plane region bounded by the graph of f(x) = e^x, the x-axis, and the vertical lines x = 0 and x = 8 using the trapezoidal method with trapezoids of equal width. Round your answer to 4 decimal places.

Question

Estimate the area of the plane region bounded by the graph of f(x) = e^x, the x-axis, and the vertical lines x = 0 and x = 8 using the trapezoidal method with trapezoids of equal width.  Round your answer to 4 decimal places.

I got the answer 6892.7480 but it was incorrect and I do not know what I did wrong. How do I find n?

Steve · Answer

the answer will depend on the number of trapezoids.
