Given the table below for selected values of f(x), use 6 left rectangles to estimate the value of.x13467910f(x)48610101216Numerical Answers Expected!Answer for Blank 1:
Accepted Solution
A:
Divide the area into 6 portions and find the sum of each one to find the value of the final integral:f(x)dx = 2(8+4)/2 + 1 (8+6)/2 + 2 (6+10)/2 + 1(10+10)/2 + 2 (10+12)/2 + 1 (12+16)/2
= 12 + 7 + 16 + 10 + 22 + 14 = 81 sq units
