The left sum would be f0+f1+f2+f3
The right sum would be f1+f2+f3+f4
The trapezoidal rule value is:
(f0+f1)/2 + (f1+f2)/2+(f2+f3)/2 +(f3+f4)/2
This would put the trapezoidal rule in the middle , which makes the answer:
Lower sum < Trapezoidal rule Value < Upper sum
400 because I said so and u are asking me is here is the answer
The answer would be the second choice. 4:5
The first one is b. The second one is d. Sorry if I’m wrong :(
