Approximate the area under the curve y = x^2 + 4 from x = 2 to x = 5 using a left sum with 6 subdivisions.
The area is approximately
Whoever helped me earlier, I did solve the equation which gave me 40.2 but the answer was 36.875, idk what I'm doing wrong (this is now a different question)

I don't know how you got 40.2, since you did not deign to show your work.
I got
A = 1/2 (f(2)+f(2.5)+f(3)+f(3.5)+f(4)+f(4.5))
= 1/2 (8 + 10.25 + 13 + 16.25 + 20 + 24.25) = 45.875
Something is wrong with this problem.
