How Do Compression Distances Affect Spring Work Calculations?

[ecoo]

Homework Statement

I reference the problem posted here: https://www.physicsforums.com/threads/work-and-spring-problem.194531/

Homework Equations

Work = Force * Distance

F = kx

The Attempt at a Solution

Wouldn't the limits of integration in part 2 be from 5 to 9, since x is the compression distance, not the length of the spring?

Thanks!
