Solving Integrals: Can't Get the Right Answer?

Click For Summary
SUMMARY

The discussion centers on solving integrals, specifically the calculation of an integral from 11 to 9.5, which the user attempts to evaluate using the equation involving f(x). The user initially calculates f(x) as 3 but encounters discrepancies when substituting values into the equation, leading to incorrect results of 25 and 21. The conversation highlights the importance of correctly interpreting integral limits and function definitions in calculus.

If you let the first attatchment be true then to find the second attachment you need to...

There was a first part to this question and I got it right. Now I try the equation and I get the integral from 11 to 9.5 = 10 + -9 + 2. Then f(x) would equal 3. If you enter that into ((9(f(x) -2) then you get 25 but that is wrong. then i tried putting 10, -9 and 2 into the equation and adding them to get 21 but that is wrong as well. I don't know where to go from here.
